Previously, the 'Add Virtual Environment' path browser started at the
filesystem root (`/`). Since virtual environments are almost always
located within the project directory, starting at the worktree root
provides feels a bit nicer to me.

Release Notes:

- Python: Improved the `Add Virtual Environment` path browser to start
at the workspace root.

The `Select Toolchain Path` picker would skip directories that exist on
my system and display `open this directory` multiple times. `Personal`
is missing:

## Problem
The existing tree-sitter queries for type imports required both name and
alias fields to match. This caused `import type { Foo }` and `import {
type Foo }` to fall back to the generic identifier/variable highlighting
instead of being colored as types.

- `import type { Foo }` → **NOT matched** (no alias)
- `import { type Foo }` → **NOT matched** (no alias)  
- `import type { Foo as Bar }` → Matched ✓
- `import { type Foo as Bar }` → Matched ✓

## Solution
Split the patterns to handle name and alias captures independently.

Summary

This PR adds the ability to quote terminal selections into Agent
threads, similar to how editor selections can be quoted. Users can now
select text in the terminal and add it as context to their agent
conversation.

### Features

- **Context menu**: Added "Add to Agent Thread" option to the terminal's
right-click menu (only shows when text is selected)
- **Keyboard shortcut**: The existing `cmd->` / `ctrl->` shortcut now
works in the terminal
- **Collapsed display**: Terminal output appears as a collapsed
"Terminal" crease in the chat, just like code references
- **Works with both thread types**: Supports both ACP-style threads
(Claude Code) and text threads

### Implementation

- Extended `quote_selection` handler to check for terminal panel focus
after checking for editor selections
- Terminal content is formatted as ` ```terminal` code blocks via new
`insert_terminal_crease` method
- Refactored crease insertion into `insert_crease_impl` helper to
support both code snippets (with `TextSnippet` icon) and terminal output
(with `Terminal` icon)
- Added automatic detection and folding of ` ```terminal` blocks in
`set_message` so terminal content stays collapsed in sent message
history
- Terminal creases use a trailing space instead of newline so cursor
behavior matches user expectations

### Demo

1. Select text in terminal
2. Right-click → "Add to Agent Thread" (or press `cmd->`)
3. Terminal content appears as collapsed "Terminal" block in chat
4. Send message - AI receives full terminal output, but chat history
shows it collapsed

### General note

I'm new to open source and the codebase in general so let me know if
anything should be different!
I tried to stay in line with other patterns I saw.
I didn't see a way to setup an end to end test with a real terminal so I
just added a unit test for the adding of the text to the chat, if it
exists and I missed it then I think the test coverage could be improved
with a test that uses a real terminal + running the command

## Summary

This PR extends the `always_allow` tool permission patterns to work with
Nushell, Elvish, and Rc shells. Previously, these shells were
incorrectly excluded because they don't use `&&`/`||` operators for
command chaining. However, brush-parser can safely parse their command
syntax since they all use `;` for sequential execution.

## Changes

- Add `ShellKind::Nushell`, `ShellKind::Elvish`, and `ShellKind::Rc` to
`supports_posix_chaining()`
- Split `ShellKind::Unknown` into `ShellKind::UnknownWindows` and
`ShellKind::UnknownUnix` to preserve platform-specific fallback behavior
while still denying `always_allow` patterns for unrecognized shells
- Add comprehensive tests for the new shell support
- Clarify documentation about shell compatibility

## Shell Notes

- **Nushell**: Uses `;` for sequential execution. The `and`/`or`
keywords are boolean operators on values, not command chaining.
- **Elvish**: Uses `;` to separate pipelines. Does not have `&&` or `||`
operators. Its `and`/`or` are special commands operating on values.
- **Rc (Plan 9)**: Uses `;` for sequential execution and `|` for piping.
Does not have `&&`/`||` operators.

## Security

Unknown shells still return `false` from `supports_posix_chaining()`, so
`always_allow` patterns are denied for safety when we can't verify the
shell's syntax.

(No release notes because granular tool permissions are still
feature-flagged.)

Release Notes:

- Added highlighting for Go directives

GitHub allows defining a default shell for all jobs on the workflow
level, which we did not use before, yet practically did when it comes
down to our usage of `named::bash`. Since this makes stuff quite
verbose, I decided on using the defaults instead so the workflows become
somewhat easier to audit when reading the generated files.

Powershell steps continue to use Powershell, only the default for bash
scripts was modified.

Previously, if a user configured `^ls` as an always-allow pattern, an
attacker could craft a command like `ls && rm -rf /` which would be
auto-approved because the regex only matched the beginning of the
command string.

Now the command is parsed into individual sub-commands (`ls`, `rm -rf
/`) and EACH sub-command must match an allow pattern for auto-approval.
This prevents shell injection attacks using operators like:
- `&&` and `||` (boolean operators)
- `;` and `&` (sequential/background execution)
- `|` (pipes)
- Newlines
- Command substitution (`$()` and backticks)
- Process substitution (`<()` and `>()`)

## Matching Logic

- **always_deny**: if ANY sub-command matches, deny the entire command
- **always_confirm**: if ANY sub-command matches, require confirmation
(unless always_deny matched, in which case deny)
- **always_allow**: ALL sub-commands must match for auto-approval
(unless always_confirm or always_deny matched, in which case defer to
those)
- If parsing fails, or if the shell is unsupported, then always_allow is
disabled for this command

As usual, `always_allow_tool_actions` supercedes all of these. If it is
`true`, then we always allow all tool calls, no questions asked.

## Shell Compatibility

The shell parser only supports POSIX-like command chaining syntax (`&&`,
`||`, `;`, `|`).

**Supported shells:** Posix (sh, bash, dash, zsh), Fish 3.0+, PowerShell
7+/Pwsh, Cmd, Xonsh, Csh, Tcsh

**Unsupported shells:** Nushell (uses `and`/`or` keywords), Elvish (uses
`and`/`or` keywords), Rc (Plan 9 shell - no `&&`/`||` operators)

For unsupported shells:
- The "Always allow" UI options are hidden for the terminal tool
- If the user has `always_allow` patterns configured in settings, they
will see a `Deny` with an explanatory error message

(No release notes because granular tool permissions are behind a feature
flag.)

Previously, each Agent panel created its own `ThreadStore` instance, so
thread history updates wouldn't sync between open windows. Users had to
close and reopen windows to see threads created in other windows.

Now `ThreadStore` is initialized once as a global and shared across all
windows. When any window saves a thread, ThreadStore::reload() calls
cx.notify(), which notifies all NativeAgentSessionList observers,
causing all windows' history views to refresh.

Note: This only works for the native Zed agent. It also is only
improving the history view (thread titles)—this PR does not sync edits
between multiple windows when the same thread is open in each.

Release Notes:

- Improved Zed agent thread history to update across all open windows

The inline git blame always calculated the difference in years for
commits based solely upon the difference between the years and not
actual time passed. This is currently somewhat unfortunate during
January, as for all dates starting from 2024 and lower, we would show `2
years ago`, even if the date was the 31st of December 2024.

This fixes/improves this to use the lower bound always instead, as I
find this much more intuitive - we can probably look into even better
formatting here at some other point.

1 years` instead of the actual `n years`.
