Closes #33286

This PR adds support for Zed's `$ZED_PICK_PID` command in debug
configurations, which allows users to select a process to attach to at
debug time. When this variable is present in a debug configuration, Zed
automatically opens a process picker modal.

Follow up for this will be integrating this variable in the task system
instead of just the debug configuration system.

Release Notes:

- Added `$ZED_PICK_PID` variable for debug configurations, allowing
users to select which process to attach the debugger to at runtime

Per
https://github.com/zed-industries/zed/discussions/23371#discussioncomment-13533635,
the issue is not new and I don't know how to solve the problem more
holistically yet.

All of the native themes don't have spec for `@diff.plus` and
`@diff.minus` leaving addition and deletion not being highlighted. For
diff file, the most valuable highlighting comes from exactly what we're
missing. Hence, I think this is worth fixing.

Perhaps, the ideal fix would be standardizing and documenting captures
such as `@diff.plus` and `@diff.minus` on
https://zed.dev/docs/extensions/languages#syntax-highlighting for theme
writers to adopt. But the existing list of captures seems to be
language-agnostic so I'm not sure if that's the best way forward.

Per
https://github.com/the-mikedavis/tree-sitter-diff/pull/18#issuecomment-2569785346,
`tree-sitter-diff`'s author prefers using `@keyword` and `@string` so
that `tree-sitter highlight` can work out of the box. So it seems to be
an ok choice for Zed.

Another approach is just adding `@diff.plus` and `@diff.minus` to the
native themes. Let me know if I should pursue this instead.

This PR places the file_name before the file_path so that when the panel
is slim it is still usable, mirrors the behaviour of the file picker
(cmd+P)

Release Notes:
-  Improved readability of files in the git changes panel

This PR builds on top of the `default_mode` feature where it was
possible to set an external agent mode as the default if you held a
modifier while clicking on the desired option. Now, if you want to have,
for example, Haiku as your default Claude Code model, you can do that.
This feature adds parity between external agents and Zed's built-in one,
which already supported this feature for a little while.

Note: This still doesn't work with external agents installed from
extensions. At the moment, this is limited to Claude Code, Codex, and
Gemini—the ones we include out of the box.

Release Notes:

- agent: Added the ability to set a model as the default for a given
built-in external agent (Claude Code, Codex CLI, or Gemini CLI).

This PR removes the old `ToggleButton` component, replacing it with the
newer `ToggleButtonGroup` component in the couple of places that used to
use it. Ended up also adding a few more methods to the newer toggle
button group so the UI for the extensions page and the debugger main
picker didn't get visually impacted much. Then, as I was already in the
extensions page, decided to bake in some reasonably small UI
improvements to it as well.

This PR introduces a new `MultiBufferOffset` new type wrapping size. The
goal of this is to make it clear at the type level when we are
interacting with offsets of a multi buffer versus offsets of a language
/ text buffer. This improves readability of things quite a bit by making
it clear what kind of offsets one is working with while also reducing
accidental bugs by using the wrong kin of offset for the wrong API.

This PR also uncovered two minor bugs due to that.

Does not yet introduce the MultiBufferPoint equivalent, that is for a
follow up PR.

We call `entry_by_path` on the `bulk_staging` anchor entry at the

`sort_by_path` is toggled on or off, we clear entries without clearing
`bulk_staging` or counts, causing that `entry_by_path` to do an out of
bounds index. Fixed by clearing `bulk_staging` as well.

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`.

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)

/>


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

This can benefit those who need to switch windows mid branch creation to
