Add permission checking to the remaining 7 tools that require granular
permissions:
- `edit_file`: Checks path against permission rules  
- `delete_path`: Checks path against permission rules
- `move_path`: Checks both source and destination paths
- `create_directory`: Checks path against permission rules
- `save_file`: Checks all paths, denies if any are blocked
- `fetch`: Checks URL against permission rules
- `web_search`: Checks query against permission rules

Each tool follows the pattern established in PR #46155 (terminal tool):
- `Allow` = proceed without prompting
- `Deny` = return error immediately
- `Confirm` = prompt user for confirmation

The deny > confirm > allow precedence is enforced by the
`decide_permission_from_settings()` function.

/>

Release Notes:

- Added structured outline for Markdown.
- Also fixed the breadcrumb display in Issue
[#45663](https://github.com/zed-industries/zed/issues/45663).

This PR creates a unified picker for all the Git-related pickers:
branch, worktree and stash. The main motivation for this is to bring
awareness and ease of access for the worktree and stash pickers that
were previously (and arguably) hidden amidst the sea of commands in the
command palette. As worktrees in particular become more relevant for
AI-related flows, having an easier way to reach for its picker will be
beneficial.

Note that the actions/commands remain the same; you can still look for
`git: worktree` or `git: view stash`. The difference is that these
actions will take you to the unified picker with the correct
corresponding active view.

Release Notes:

- Git: Unify the branch, worktree, and stash pickers into one, making it
easier to find and access them from one another.

New workspace/window creates a different `WeakEntity<WorktreeStore>` for
the same path, which was not considered before.

`use smol::channel::{Receiver, Sender};` do not propagate the value
change to all receivers, hence only one language server received the
"worktree trusted" message.
The fix uses `watch` kind of channels instead, and cleans up its state
more eager to rely on the sender drop as another form of notification.

Release Notes:

- Fixed groups of language servers not starting after worktree trust
approval

Stumbled across this upon a PR review - `unfold_ranges` takes a slice of

## Summary

When using applications that hide the terminal cursor (e.g., via ANSI
escape sequence `\e[?25l`), the IME candidate window appeared at the
bottom-left of the screen, and the composition text was not displayed at
all. This affects tools like Claude Code that hide the cursor during
operation.

The root cause was that cursor position calculation was skipped when the
cursor shape was `Hidden`. This fix separates cursor visibility from IME
position calculation by always computing cursor bounds for IME
positioning.

TL;DR: There was a closed issue 7 hours ago that changed ashpd version,
it needed another bump.

A dependency of gpui called ashpd has a fix in v0.12.1, GPUI has the
0.12 version. After forking zed and patching the gpui source to be mine
with 0.12.1 it was able to use GPUI as a dependency and compile the
project. The error I was getting and the recomendation to do this PR can
be seen in this [closed issue from
ashpd](https://github.com/bilelmoussaoui/ashpd/issues/325).

After changing the dependecy I hit cargo check:
```bash
   Finished `dev` profile [unoptimized + debuginfo] target(s) in 4m 24s
```

And cargo run:
```bash

Closes #40110

  Changes:
- `DeleteToPreviousSubwordStart` now deletes `\n` separately from
preceding subwords and whitespace.
- `DeleteToNextSubwordEnd` now deletes `\n` and any following whitespace
separately from subsequent subwords.
- Added an `ignore_newlines` flag to both actions to optionally retain
the old behavior.

These modifications align the subword commands with their word
counterparts and with other popular editors like VSCode and Sublime.

Related to: https://github.com/zed-industries/zed/pull/16848

  Release Notes:

- Improved `DeleteToPreviousSubwordStart` and `DeleteToNextSubwordEnd`
interactions around newlines. You can opt-in into the previous behavior
by adding `{"ignore_newlines": true}` to either action's binds in your
keymap.

Previously, a new composition string was processed before a new
composition result. Thus, in the case that a keystroke creates a new
composition result and composition string, the processing of the new
result would overwrite the new string, even though they should both be
displayed. Processing them in the reverse order fixes this issue.
 
Fixes #42201

Additionally: while fixing this issue, I discovered that the Japanese
IME sometimes moves the cursor far away from the inserted text. WPF
works around this issue by only respecting the IME's requested cursor
position if it's adjacent to uncommitted text. So, we copy this
workaround.

PR #46306 changed cancellation to wait for tools to complete before
returning. This was correct behavior - it allows tools like terminal to
capture their output on cancellation. The real issue was that many tools
didn't check for cancellation, so they would continue running until they
finished.

## The Problem

When the user pressed Escape to cancel during a tool operation, tools
would continue running because they never checked for the cancellation
signal. The thread correctly waited for tools to complete (so terminal
could capture output), but tools like edit_file, grep, fetch, etc. would
just keep going.

## The Fix

Add cancellation handling to all tools using the same pattern as
`terminal_tool`: use `select!` to race between the tool's main work and
`event_stream.cancelled_by_user()`. When cancelled, tools break out of
their loops or return early.

## All Tools Now Cancellation-Aware

| Tool | Change |
|------|--------|
| `edit_file_tool` | Checks cancellation in edit event processing loop |
| `terminal_tool` | Already handled cancellation |
| `grep_tool` | Checks cancellation in search result iteration loop |
| `fetch_tool` | Checks cancellation during HTTP fetch |
| `web_search_tool` | Checks cancellation during web search |
| `find_path_tool` | Checks cancellation during path search |
| `read_file_tool` | Checks cancellation during buffer open |
| `copy_path_tool` | Checks cancellation during file copy |
| `move_path_tool` | Checks cancellation during file move/rename |
| `delete_path_tool` | Checks cancellation during delete operation |
| `create_directory_tool` | Checks cancellation during directory
creation |
| `save_file_tool` | Checks cancellation during buffer open and save |
| `restore_file_from_disk_tool` | Checks cancellation during buffer open
and reload |
| `open_tool` | Checks cancellation during authorization |
| `diagnostics_tool` | Checks cancellation during buffer open |
| `ContextServerTool` (MCP) | Checks cancellation during external server
calls |

**Synchronous tools (no async work, return immediately):**
- `list_directory_tool` - Reads worktree snapshot synchronously
- `now_tool` - Returns current time immediately
- `thinking_tool` - Returns immediately

## MCP Tools Automatically Handled

MCP tools (user-defined tools via context servers) are now automatically
cancellation-aware without any user action. The `ContextServerTool`
wrapper races the external server request against
`event_stream.cancelled_by_user()`.

## Testing

- Added `CancellationAwareTool` test helper that mirrors the
cancellation pattern
- Updated `test_cancellation_aware_tool_responds_to_cancellation` to
properly await the cancel task and verify the tool detected cancellation

Release Notes:

- Fixed a regression where pressing Escape wouldn't immediately cancel
in-progress tool operations

This PR makes it so we use a proper type for the Responses API `input`
rather than a `serde_json::Value`.

It should have never used `serde_json::Value` to begin with.

Release Notes:

## Motivation

This PR unifies the async execution infrastructure between GPUI and
other components that depend on the `scheduler` crate (such as our cloud
codebase). By having a scheduler that lives independently of GPUI, we
can enable deterministic testing across the entire stack - testing GPUI
applications alongside cloud services with a single, unified scheduler.

## Summary

This PR completes the integration of the `scheduler` crate into GPUI,
unifying async execution and enabling deterministic testing of GPUI
combined with other components that depend on the scheduler crate.

## Key Changes

### Scheduler Integration (Phases 1-5, previously completed)
- `TestDispatcher` now delegates to `TestScheduler` for timing, clock,
RNG, and task scheduling
- `PlatformScheduler` implements the `Scheduler` trait for production
use
- GPUI executors wrap scheduler executors, selecting `TestScheduler` or
`PlatformScheduler` based on environment
- Unified blocking logic via `Scheduler::block()`

### Dead Code Cleanup
- Deleted orphaned `crates/gpui/src/platform/platform_scheduler.rs`
(older incompatible version)

## Intentional Removals

### `spawn_labeled` and `deprioritize` removed
The `TaskLabel` system (`spawn_labeled`, `deprioritize`) was removed
during this integration. It was only used in a few places for test
ordering control.

cc @maxbrunsfeld @as-cii - The new priority-weighted scheduling in
`TestScheduler` provides similar functionality through
`Priority::High/Medium/Low`. If `deprioritize` is important for specific
test scenarios, we could add it back to the scheduler crate. Let me know
if this is blocking anything.

### `start_waiting` / `finish_waiting` debug methods removed
Replaced by `TracingWaker` in `TestScheduler` - run tests with
`PENDING_TRACES=1` to see backtraces of pending futures when parking is
forbidden.

### Realtime Priority removed
The realtime priority feature was unused in the codebase. I'd prefer to
reintroduce it when we have an actual use case, as the implementation
(bounded channel with capacity 1) could potentially block the main
thread. Having a real use case will help us validate the design.

## Testing
- All GPUI tests pass
- All scheduler tests pass
- Clippy clean

this feature).


https://github.com/user-attachments/assets/94ece12c-3071-4a07-a04d-8d89e10fd59e

Release Notes:

- Added the ability to right-click the breadcrumb button when it's a
file path and copy the path.

## Summary

Fixes #33633 - folds corrupting after external file modifications.

The existing fold persistence stored raw byte offsets, which become
stale when files are modified externally (git operations, other editors,
sync tools). This caused folds to capture wrong content on restore -
users reported "wrong lines getting folded" with systematic offsets.

**Solution: Content fingerprinting**
- Store 32-byte content samples at fold boundaries
- On restore, validate fingerprints match; if not, search buffer for new
positions
- Handles edge cases: short folds (< 32 bytes), duplicate content,
boundary positioning

**Bonus fix: Ungraceful exit survival**
- Entity IDs change between sessions, but workspace cleanup's CASCADE
DELETE was wiping folds before new editors could save
- Now migrates folds to new entity_id immediately after restore

## Test plan

- [x] Unit test for fingerprint storage/retrieval
(`test_save_and_get_editor_folds_with_fingerprints`)
- [x] Manual test: fold sections, add content at file start externally,
reopen → folds restore at correct positions
- [x] Manual test: fold sections, Ctrl+C, reopen → folds survive
- [x] Existing fold tests pass (`cargo test -p editor`)

Summary
This PR fixes an issue where Python virtual environments (`venv`, `uv`,
etc.) were not automatically activated when opening a terminal using
PowerShell 7.

`ShellKind` distinguishes between the legacy Windows PowerShell

(`ShellKind::Pwsh`). Previously, the logic in
`resolve_venv_activation_scripts` only checked for
`ShellKind::PowerShell`, causing `activate.ps1` resolution to fail for
`Pwsh` users.
This change adds `ShellKind::Pwsh` to the resolution list, mapping it to
`activate.ps1` just like the legacy PowerShell.

Release Notes:

- Fixed Python virtual environments not automatically activating in
PowerShell 7

Add a `match_quotes` parameter to the `vim::Matching` action that
controls whether the `%` motion should treat quote characters (', ", `)
as matching pairs.

In Neovim, `%` only matches bracket pairs (([{}])), not quotes. Zed's
existing behavior includes quote matching, which some users prefer. To
preserve backwards compatibility while allowing users to opt into
Neovim's behavior, this PR:

1. Adds an optional `match_quotes` boolean parameter to the
   `vim::Matching` action
2. Updates the default vim keymap to use ["vim::Matching", {
   "match_quotes": true }], preserving Zed's current behavior
3. Users who prefer Neovim's behavior can rebind `%` in their keymap:

```
{
    "context": "VimControl && !menu",
    "bindings": {
        "%": ["vim::Matching", { "match_quotes": false }]
    }
}
```

When `match_quotes` is `false`, the `%` motion will skip over quote
characters and only match brackets/parentheses, matching Neovim's
default behavior.

Release Notes:

- vim: Added match_quotes parameter to the vim::Matching action to control
whether % matches quote characters

The visual test infrastructure changes in #46324 accidentally switched
from `settings::init(cx)` to `SettingsStore::test(cx)`, which uses
Courier font instead of the real Zed fonts (IBM Plex Sans / Lilex).

This restores the correct font loading:
1. Load embedded fonts with `Assets.load_fonts(cx)`
2. Use `settings::init(cx)` to get the real default settings with proper
fonts

This pollutes tasks and similar with a `connection closed` message
otherwise.

Release Notes:

- Fixed terminal tool for agents ending with `connection closed` on
remote hosts polluting context

This happens when a user's default branch has different remote and local
versions on their system. Because we would get a diff using just a
branch name without including it's remote name as well

This is a better default because it's far less confusing from a user's
perspective to debug what's going on.

Release Notes:

- git: Fix BranchDiff showing incorrect diffs when default local branch
is out of sync with the remote default branch
