rebased https://github.com/zed-industries/zed/pull/48161

Release Notes:

- Updated text rendering dependency to fix and improve font ligature
support

Implements the enhancement requested in #24655 - enables tab switcher to
show all open files across all panes deduped. It's called "follow mode"
because whichever is the active pane is ALWAYS where the file, terminal,
etc will be opened from the tab switcher (not married to this mode
name).

Adds `follow_mode: true` option to `tab_switcher::ToggleAll`. When
enabled:

- **Shows all tabs across panes** - Same file in multiple panes appears
once (deduped by path)
- **Opens in active pane** - Selecting a file opens it in current pane,
creating independent editor instances
- **Moves terminals** - Non-file items (terminals, multibuffers) move to
current pane instead of duplicating
- **Preview & restore** - Navigate with arrow keys / tab to preview,
Escape restores original state

Intended for vim/helix `:buffers` command workflow while respecting
Zed's tab-based paradigm.

### Usage

```json
["tab_switcher::ToggleAll", {"follow_mode": true}]
```

### Implementation

**Preview pattern:** Clone item handles during navigation, clean up on
dismiss
- **Files**: Preview with cloned handle, confirm closes preview and
opens fresh (independent editors)
- **Terminals**: Preview with cloned handle, confirm removes from source
(moves to current pane)

**Key technical details:**
- Ignore workspace events during follow mode to prevent list re-sorting
from preview operations
- Preserve preview tab status on confirm
- Close operations remove from all panes in follow mode
- Remove from source before activating to ensure correct focus
management

### Test Coverage

21 tests total (14 new follow mode tests):
- File behavior: deduplication, independent editors, preview status
preservation, close behavior
- Non-file behavior: terminal movement, focus management, single pane
scenarios
- General: MRU stability, restore on dismiss

### Release Notes

- Added `follow_mode` option to `tab_switcher::ToggleAll` for vim-style
buffer list showing all deduped open files across panes opening in
active pane

## Q&A

**Q: Why not tie this to vim mode?**

A: This feature is different enough from vim/helix buffer behavior that
I opted not to couple them. It is an approximation using Zed's tab
switcher/picker and would take architectural changes to implement real
vim/helix buffers. Additionally, both follow mode and regular tab
switcher mode are useful window/tab management workflows that vim or
non-vim users may want regardless of their editing mode preference.

**Q: How to use this?**

A: For a vim/helix-like workflow:

1. **Bind the follow mode tab switcher** - Add to your keymap:
   ```json
   {
     "context": "Workspace",
     "bindings": {
       "cmd-i": ["tab_switcher::ToggleAll", {"follow_mode": true}]
     }
   }
   ```

2. **Hide the tab bar (optional)** - Add to settings:
   ```json
   {
     "tab_bar": {
       "show": false
     }
   }
   ```

3. **Move tabs to other pane on close (optional)** - Add to your keymap
to join tabs into next pane when closing:
   ```json
   {
     "context": "Pane",
     "bindings": {
       "cmd-w": "pane::JoinIntoNext"
     }
   }
   ```

This makes closing a tab behave more like vim's split closure - items
move to the adjacent pane instead of being closed.

If you find that you'd rather have the tab bar visible, there's a pretty
good chance you don't need/want this feature. Vim/helix don't have
visible tab bars, so this feature is primarily for users who want that
sort of experience where buffers are not tied to a specific split/pane
and closing a split does not impact the available buffers.

## Future Work

A few additional features could make for more complete vim/helix-like
buffer workflow:

**`:bd` (buffer delete) improvements:**
- Should close the buffer from ALL panes, not just the current one
- Current implementation: `workspace::CloseActiveItem` only closes in
current pane
- Needed: New action like `workspace::CloseActiveItemAcrossPanes` and/or
update vim command mapping

**`:q` (quit) improvements:**
- Should close the split/pane while preserving its tabs
- Behavior: merge tabs into next pane (like `pane::JoinIntoNext`),
unless it's the last pane
- Last pane: close the pane and all its items
- Current implementation: `workspace::CloseActiveItem` closes active
item, not the pane
- Needed: New action or pane closure logic that moves tabs before
closing

These are complementary to this feature and can be done as separate PRs.

Release Notes:

- Add `tab_switcher::ToggleUnique` to allow a more vim-like tab
switching experience.

We're not actually using adaptive thinking yet.

Release Notes:

- N/A

This PR removes the `fn name()` default method from the `AgentTool`
trait (which just returned `Self::NAME`) and replaces all call sites
with direct use of the `NAME` associated constant. This lets us use it
as a single source of truth in macros that want to access it at compile
time.

This PR also replaces hardcoded tool name string literals throughout the
codebase with the corresponding `NAME` constants, so tool name
references stay in sync if a tool is renamed.

Intentionally not changed:

- **Display strings** like `"Thinking"` and `"Subagent"` (user-facing UI
labels)
- **Serde attributes** like `#[serde(rename = "thinking")]` (wire
format)
- **The test assertion** `assert_eq!(SubagentTool::NAME, "subagent")`
(replacing the literal would make it tautological)
- **MCP server names** like `"mcp:srv:terminal"` (not tool identifiers)

Release Notes:

- N/A

This adds Claude Opus 4.6 as a new Anthropic model, along with 1M
context window variants for both Opus 4.6 and Sonnet 4.5.

## Opus 4.6

Adds `ClaudeOpus4_6` and `ClaudeOpus4_6Thinking` with the same
properties as other Claude 4+ models (200k context, 8192 max output
tokens, fine-grained tool streaming beta header).

## 1M context variants

Adds 1M context window variants for Sonnet 4.5 and Opus 4.6. These are
identical to their base models except:
- Context window is 1,000,000 tokens instead of 200,000
- They send the `context-1m-2025-08-07` beta header

Release Notes:

- Added Claude Opus 4.6
- Now Claude Opus 4.6 and Sonnet 4.5 BYOK models support variations that
have context windows of 1 million tokens (and have different pricing)

Release Notes:

- Fixed `HelixSelectLine` with an empty first line and a pre-existing
selection.

This moves some more of our CI jobs over to xtask and gh-workflow. This
primarily originated from the current GitHub actions outage to move
these actions over to Namespace runners. However, while I was at it I
decided to move these over to gh_workflow, as we benefit from sharing
more stuff across these files and less hacking around in YAML-files
directly.

Apple recommends checking the system’s thermal state and adjusting
behavior to reduce resource usage, giving the system a chance to cool
down. While this API is macOS-specific, the same idea likely applies to
other platforms - those are intentionally out of scope for this PR.

As a first step, we cap the frame rate at 60 fps when the system reports
a critical thermal state. In that situation, pushing higher frame rates
doesn’t buy us anything and just adds more heat. This also gives us a
hook for future improvements, like reducing other work when the system
is under sustained thermal pressure.

Release Notes:

- Zed now reduces resource usage when the system is under high thermal
stress

The other day I was testing the debugging feature and I noticed a
**very** small visual bug. When you click on the breakpoint circle to
set a breakpoint, the breakpoint color remains in the wrong state until
the mouse moves.

After debugging for a while, I noticed that the issue was that the
PhantomVariableIndicator variable attribute
`collides_with_existing_breakpoint` was not being updated until the
mouse moved. With the following change, the attribute is updated when
the user clicks the breakpoint, toggleling tha attribute.

### Prior behaviour:

https://github.com/user-attachments/assets/3dfa8e25-e970-49a3-8e87-0ecadabb3a3c

As you can see in the video, prior to this change, the breakpoint would
only change to the correct color when the mouse moved.
 
### New behaviour

https://github.com/user-attachments/assets/356e84dc-42e5-4440-afab-0fbc4b3a1f0a

With this new change, the breakpoint updates right after the user
clicks, no need to move the mouse.

### Disclaimers

- I'm new to this codebase, so any feedback is extremely welcomed! If
you know of a better place where this could be handled, let me know and
I'll explore further.

Currently we always compute breadcrumbs and sticky headers on every
editor paint which is not cheap to do especially in bigger files, moving
this off to be computed on event handling where they change and then
caching them can save serveral milliseconds per render in bigger files.

This also puts matching brackets refreshing and document highlights on a
background task, as this tends to block the main task for prolonged time
as well.

## Problem

Zed's terminal permission system validates commands using regex patterns
against string representations of parsed commands. The
`SimpleCommand::to_string()` method in brush-parser preserves the raw
lexical form including shell quotes, causing pattern matching to fail on
obfuscated commands.

For example, all of these are semantically equivalent to `rm -rf /` in
POSIX shells, but produced different strings from `to_string()` that
bypassed the hardcoded deny pattern `rm\s+(-[rf]+\s+)*/\s*$`:

| Input | `extract_commands()` returned | Matched deny pattern? |
|---|---|---|
| `rm -rf /` | `"rm -rf /"` | ✅ Yes |
| `rm -rf '/'` | `"rm -rf '/'"` | ❌ No |
| `'rm' -rf /` | `"'rm' -rf /"` | ❌ No |
| `r'm' -rf /` | `"r'm' -rf /"` | ❌ No |
| `rm -r'f' /` | `"rm -r'f' /"` | ❌ No |
| `rm -rf \/` | `"rm -rf \\/"` | ❌ No |

Both hardcoded deny patterns (Phase 2, which operates on extracted
sub-commands) and user-configured `always_deny` patterns were affected.

## Fix

Replace the `simple_command.to_string()` call in
`extract_commands_from_simple_command` with manual construction that:

1. Iterates the command name (`word_or_name`) and word arguments from
the suffix
2. Normalizes each word by parsing it into `WordPiece`s via
`brush_parser::word::parse`
3. Reconstructs the semantic (unquoted) value from each piece:
   - `Text` — used as-is
- `SingleQuotedText` — used as-is (brush-parser already strips the
wrapping quotes)
- `EscapeSequence` — leading `\` stripped to produce the unescaped
character
- `AnsiCQuotedText` — used as-is (brush-parser already evaluates
`$'...'`)
- `DoubleQuotedSequence` / `GettextDoubleQuotedSequence` — inner pieces
recursively normalized
   - `TildePrefix` — preserved as `~` + suffix
- `ParameterExpansion` / `CommandSubstitution` /
`BackquotedCommandSubstitution` / `ArithmeticExpression` — original
source text preserved so patterns like `\$HOME` and `\${HOME}` continue
to match
4. Joins normalized words with spaces

Falls back to the raw `word.value` if word parsing fails.

## Cross-shell safety

The normalization operates on POSIX-parsed ASTs (brush-parser uses POSIX
grammar), so it applies POSIX quoting rules. For non-POSIX shells
(Nushell, PowerShell, Xonsh, Elvish, etc.) where quoting semantics
differ, any mismatch results in false positives (overly cautious
denials), never false negatives. This is the correct error direction for
a security feature. When brush-parser fails to parse a non-POSIX
command, `extract_commands` returns `None` and the existing fallback
(raw-string matching with `allow_enabled=false`) handles it.

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

`find_target()` failed to match numbers followed by a dot and a
non-digit (e.g. `1. item`), because the dot unconditionally reset
the scan state, discarding the number. Additionally, numbers at the
start of non-first lines were missed because the backward scan
stopped on the preceding newline and the forward scan immediately
broke on it.

Adds `checkerboard` to `Background`, and use it for the side-by-side

Note that, since the blockmap can contain multiple `Spacer`s without any

in between, we ensure that the checkerboard pattern always shows an even

discontinuities
in the pattern when this happens.
