This PR restructures the subcommands in `zeta-cli`, so that the
prediction engine (currently `zeta1` vs `zeta2`) is no longer the
highest order subcommand. Instead, there is just one layer of
subcommands: `eval`, `predict`, `context`, etc. Within these commands,
there are flags for using `zeta1`, `zeta2`, and now `sweep`.

Calloop (used by our linux executor) was running all futures regardless
of how long they take. Unfortunaly some of our futures are rather busy
and take a while (>10ms).

Running all of them froze the editor for multiple seconds or even
minutes when opening a large project diff (git reset HEAD~2000 in
chromium for example).

Lots of folks were accidentally clicking this. Even though it’s the
default in macOS Finder, it’s a good idea to not have it as the default
for us.

Release Notes:

- Removed the default `cmd-opt-.` binding for toggling hidden files in
the Project Panel so it’s harder to hide them by accident.

An attempt to re-land https://github.com/zed-industries/zed/pull/41043
Part of https://github.com/zed-industries/zed/issues/5259 (as `>>>`
forms a ligature that we need to break into differently colored tokens)

Before:

/>


When certain combination of characters forms a ligature, it takes the
color of the first character.
Even though the runs are split already by color and other properties,
the underlying font system merges the runs together.

Attempts to modify color and other, unrelated to font size, parameters,
did not help on macOS, hence a somewhat odd approach was taken: runs get
interleaved font sizes: normal and "normal + a tiny bit more".
This is the only option that helped splitting the ligatures, and seems
to render fine.

Release Notes:

- Fixed ligatures forming between different text kinds

The bug is in the `place_near` logic, specifically the
`!row_block_types.contains_key(&(row - 1))` check. The problem isn’t
really that condition itself, but it’s that it relies on
`row_block_types`, which does not take into account that upon block
resizes, subsequent block start row moves up/down. Since `place_near`
depends on this incorrect map, it ends up causing incorrect resize syncs
to the block map, which then triggers more bad recursive calls. The
reason it worked till now in most of the cases is that recursive resizes
eventually lead to stabilizing it.

Before `place_near`, we never touched `row_block_types` during the first
prepaint pass because we knew it was based on outdated heights. Once all
heights are finalized, using it is fine.

The fix is to make sure `row_block_types` is accurate from the very
first prepaint pass by keeping an offset whenever a block shrinks or
expands. Now ideally it should take only one subsequent prepaint. But
due to shrinking, new custom/diagnostics blocks might come into the view
from below, which needs further prepaint calls for resolving. Right now,
tests pass after 2 subsequent prepaint calls. Just to be safe, we have
set it to 5.

I was trying to use Zed for Rust debugging on windows, but was getting
this warning in debugger console: "Could not initialize Python
interpreter - some features will be unavailable (e.g. debug
visualizers)."
As the warning suggests this led to bad debugging experience where the
variables were not visualized properly in the "Variables" panel.

After some investigation I found that the problem is that Zed silently
failed to extract all files from the debug adapter package
(https://github.com/vadimcn/codelldb/releases/download/v1.11.8/codelldb-win32-x64.vsix).
Particularly `python-lldb` folder was missing, which caused the warning.
The error occurred here:

https://github.com/zed-industries/zed/blob/cf7c64d77f1806cdd34b3812bbf27681fb3cb905/crates/util/src/archive.rs#L47
And then gets ignored here:

https://github.com/zed-industries/zed/blob/cf7c64d77f1806cdd34b3812bbf27681fb3cb905/crates/dap/src/adapters.rs#L323-L326
The simple fix is to update `async_zip` crate to version 0.0.18 where
this issue appears to be fixed. I also added logging instead of silently
ignoring the error, as I believe that would have helped to catch it
earlier.

To reproduce the original issue you can try to follow these steps:
0. (Optional) Remove/rename old codelldb adapter at
`%localappdata%\Zed\debug_adapters\CodeLLDB`. Restart Zed.
1. Create a simple Rust project. Make sure you use gnu toolchain (target
`x86_64-pc-windows-gnu`)
```rust
fn world() -> String {
    "world".into()
}

fn main() {
    let w = world();
    println!("hello {}", w);
}
```

2. Put a breakpoint on line 7 (`println`)
3. In the command palette choose "debugger: start" and then select "run
*crate name*"

Small QOL improvement for branch picker to only dismiss when focus lost
in active window.
This can benefit those who need to switch windows mid branch creation to
fetch correct jira ticket number or etc.

Added `window.is_active_window()` guard in `picker.rs` -> `cancel` event

Release Notes:
- (Let's Git Together) Fixed a behavior where pickers would
automatically close upon the window becoming inactive.

We install phpactor by default, but on windows it doesn't work out of
the box (see
[here](https://github.com/phpactor/phpactor/discussions/2579) for
details). For now we'll default to using intelephense, but in the future
we'd like to switch back if phpactor lands windows support given that
it's open source.

Release Notes:

- Added the newly released Gemini 3 Pro Preview Model


https://docs.cloud.google.com/vertex-ai/generative-ai/docs/models/gemini/3-pro

https://github.com/zed-industries/zed/pull/40883 implemented this
incorrectly. It was marking a random background thread as a wasm thread
(whatever thread picked up the wasm epoch timer background task),
instead of marking the threads that actually run the wasm extension.

This has two implications:
1. it didn't prevent extension panics from tearing down as planned
2. Worse, it actually made us hide legit panics in sentry for one of our
background workers.

Now 2 still technically applies for all tokio threads after this, but we
basically only use these for wasm extensions in the main zed binary.

- Fixed extension panics crashing Zed on Linux

This PR updates window background rendering to use the **official DWM
backdrop API** (`DwmSetWindowAttribute`) instead of the legacy
`SetWindowCompositionAttribute`.
It also adds **Mica** and **Mica Alt** options to
`WindowBackgroundAppearance` for native Windows 11 effects.

### Motivation

Enables modern, stable, and GPU-accelerated backdrops consistent with
Windows 11’s Fluent Design.
Removes reliance on undocumented APIs while maintaining backward
compatibility with older Windows versions.

### Changes

* Added `MicaBackdrop` and `MicaAltBackdrop` variants.
* Switched to DWM API for applying backdrop effects.
* Verified fallback behavior on Windows 10.

### Release Notes:

- Added `WindowBackgroundAppearance::MicaBackdrop` and
`WindowBackgroundAppearance::MicaAltBackdrop` for Windows 11 Mica and
Mica Alt window backdrops.

### Screenshots

- `WindowBackgroundAppearance::Blurred`

The model often uses the wrong closing tag, or has spaces around the
closing tag name. This PR makes it so that opening tags are treated as
authoritative and any closing tag with the name `new_text` `old_text` or
`edits` is accepted based on depth. This has the additional benefit that
the parsing is more robust with contents that contain `new_text`
`old_text` or `edits. I.e. the following test passes

```rust
    #[test]
    fn test_extract_xml_edits_with_conflicting_content() {
        let input = indoc! {r#"
            <edits path="component.tsx">
            <old_text>
            <new_text></new_text>
            </old_text>
            <new_text>
            <old_text></old_text>
            </new_text>
            </edits>
        "#};

        let result = extract_xml_replacements(input).unwrap();
        assert_eq!(result.file_path, "component.tsx");
        assert_eq!(result.replacements.len(), 1);
        assert_eq!(result.replacements[0].0, "<new_text></new_text>");
        assert_eq!(result.replacements[0].1, "<old_text></old_text>");

Release Notes:

### What this solves

This PR adds support for HTTP and SSE (Server-Sent Events) transports to
Zed's context server implementation, enabling communication with remote
MCP servers. Currently, Zed only supports local MCP servers via stdio
transport. This limitation prevents users from:

- Connecting to cloud-hosted MCP servers
- Using MCP servers running in containers or on remote machines
- Leveraging MCP servers that are designed to work over HTTP/SSE

### Why it's important

The MCP (Model Context Protocol) specification includes HTTP/SSE as
standard transport options, and many MCP server implementations are
being built with these transports in mind. Without this support, Zed
users are limited to a subset of the MCP ecosystem. This is particularly
important for:

- Enterprise users who need to connect to centralized MCP services
- Developers working with MCP servers that require network isolation
- Users wanting to leverage cloud-based context providers (e.g.,
knowledge bases, API integrations)

### Implementation approach

The implementation follows Zed's existing architectural patterns:

- **Transports**: Added `HttpTransport` and `SseTransport` to the
`context_server` crate, built on top of the existing `http_client` crate
- **Async handling**: Uses `gpui::spawn` for network operations instead
of introducing a new Tokio runtime
- **Settings**: Extended `ContextServerSettings` enum with a `Remote`
variant to support URL-based configuration
- **UI**: Updated the agent configuration UI with an "Add Remote Server"
option and dedicated modal for remote server management

### Changes included

- [x] HTTP transport implementation with request/response handling
- [x] SSE transport for server-sent events streaming
- [x] `build_transport` function to construct appropriate transport
based on URL scheme
- [x] Settings system updates to support remote server configuration
- [x] UI updates for adding/editing remote servers
- [x] Unit tests using `FakeHttpClient` for both transports
- [x] Integration tests (WIP)
- [x] Documentation updates (WIP)

### Testing

- Unit tests for both `HttpTransport` and `SseTransport` using mocked
HTTP client
- Manual testing with example MCP servers over HTTP/SSE
- Settings validation and UI interaction testing

### Screenshots/Recordings

[TODO: Add screenshots of the new "Add Remote Server" UI and
configuration modal]

### Example configuration

Users can now configure remote MCP servers in their `settings.json`:

```json
{
  "context_servers": {
    "my-remote-server": {
      "enabled": true,
      "url": "http://localhost:3000/mcp"
    }
  }
}
```

### AI assistance disclosure

I used AI to help with:

- Understanding the MCP protocol specification and how HTTP/SSE
transports should work
- Reviewing Zed's existing patterns for async operations and suggesting
consistent approaches
- Generating boilerplate for test cases
- Debugging SSE streaming issues

All code has been manually reviewed, tested, and adapted to fit Zed's
architecture. The core logic, architectural decisions, and integration
with Zed's systems were done with human understanding of the codebase.
AI was primarily used as a reference tool and for getting unstuck on
specific technical issues.

Release notes:
* You can now configure MCP Servers that connect over HTTP in your
settings file. These are not yet available in the extensions API.
  ```
  {
    "context_servers": {
      "my-remote-server": {
        "enabled": true,

      }
    }

Fixes #42945

## Problem
When opening a single file via command line (e.g., `zed
~/Downloads/file.txt`), the terminal panel was opening in the root
directory (/) instead of the file's directory.

## Root Cause
The code only checked for active project directory, which returns None
when a single file is opened. Additionally, file worktrees weren't
handling parent directory lookup.

## Solution
Added fallback logic to use the first project directory when there's no
active entry, and made file worktrees return their parent directory
instead of None.

## Testing
- All existing tests pass
- Added test coverage for file worktree scenarios
- Manually tested with `zed ~/Downloads/file.txt` - terminal now opens
in correct directory

This improves the user experience for users who frequently open single
files from the command line.

## Release Notes

- Fixed terminal opening in root directory when editing single files
from the command line
