This PR improves the toggle button group to be more responsive across
different layouts. This is accomplished by ensuring each button takes up
the same amount of space in the parent containers layout.

Ideally, this should be done with grids instead of a flexbox container,
as this would be much better suited for this purpose. Yet, since we lack
support for this, we go with this route for now.

Closes #32538

This PR adjusts the defaults for splitting panes along the horizontal
and vertical actions. Based upon user feedback, the adjusted values seem
more reasonable as default settings, hence, go with these instead.

Release Notes:

- Changed the default split directions for the `pane: split horizontal`
and `pane: split vertical` actions. You can restore the old behavior by
modifying the `pane_split_direction_horizontal` and
`pane_split_direction_vertical` values in your settings.

Release Notes:

- Added `reasoning_effort` support to custom models

Tested using the following config:
```json5
  "language_models": {
    "openai": {
      "available_models": [
        {
          "name": "gpt-5-mini",
          "display_name": "GPT 5 Mini (custom reasoning)",
          "max_output_tokens": 128000,
          "max_tokens": 272000,
          "reasoning_effort": "high" // Can be minimal, low, medium (default), and high
        }
      ],
      "version": "1"
    }
  }
```

Docs:
https://platform.openai.com/docs/api-reference/chat/create#chat_create-reasoning_effort

This work could be used to split the GPT 5/5-mini/5-nano into each of
it's reasoning effort variant. E.g. `gpt-5`, `gpt-5 low`, `gpt-5
minimal`, `gpt-5 high`, and same for mini/nano.

Release Notes:

* Added a setting to control `reasoning_effort` in OpenAI models

Closes #ISSUE

The fix was changing the picker kind we used from `list` variant to a
`uniform` list

`Picker::list()` still has a bug where it's unable to scroll to it's
selected entry when the list is first openned. This is likely caused by
list not knowing the pixel offset of each element it would have to
scroll pass to get to the selected element

Only cross-compilation targets need to be listed in the rust toolchain.
So we only need to list the wasi target for extensions, and the musl
target for the linux remote server. Previously, we were causing mac,
linux, and windows target to get installed onto all developer
workstations, which is unnecessary.

Release Notes:

- N/A

An alternative might be to adjust the logic to not nest items when their
ranges are the same, but then clicking them doesn't work properly /
moving the cursor does not change which is selected. This could probably
be made to work with some extra logic there, but it seems overkill.

The downside of fixing it at the query level is that other parts of the
declaration are not inside the item range. This seems to be fine for
single line declarations - the nearest outline item is highlighted.
However, if a part of the declaration is not included in an item range
and is on its own line, then no outline item is highlighted.

Release Notes:

- Outline Panel: Fixed nesting of var and field declarations with
multiple identifiers in Go and C++

Release Notes:

- Don't auto-retry for "payment required" or "model request limit
reached" errors (since retrying won't help)

1. Extension loaded events are now condensed into a single event with a
Vec of (extension_id, extension_version) called id_and_versions.
2. Editor Saved & AutoSaved are merged into a singular event with a type
field that is either "manual" or "autosave”.
3. Editor Edited event will only fire once every 10 minutes now.
4. Editor Closed event is fired when an editor item (tab) is removed
from a pane

Closes #34374

This is a leftover issue from #34374. Back in #34374, I wanted to use
DirectX to handle vsync, after all, that’s how 99% of Windows apps do
it. But after discussing with @maxbrunsfeld , we decided to stick with
the original vsync approach given gpui’s architecture.

In my tests, there’s no noticeable performance difference between this
PR’s approach and DirectX vsync. That said, this PR’s method does have a
theoretical advantage, it doesn’t block the main thread while waiting
for vsync.


The only difference is that in this PR, on Windows 11 we use a newer API
instead of `DwmFlush`, since Chrome’s tests have shown that `DwmFlush`
has some problems. This PR also removes the use of
`MsgWaitForMultipleObjects`.

Update both `:tabedit` and `:tabnew` commands in order to support a
single argument, a filename, that, when provided, ensures that the new
tab either opens an existing file or associates the new tab with the
filename, so that when saving the buffer's content, the file is created.

Relates to #21112

In the same vein as #29538, the "Services" menu on macOS depended on the
text being exactly "Services", not allowing for i18n of the menu name.

This PR introduces a new menu type called `OsMenu` that defines a
special menu that can be populated by the system. Currently, it takes
one enum value, `ServicesMenu` that tells the system to populate its
contents with the items it would usually populate the "Services" menu
with.

An example of this being used has been implemented in the `set_menus`
example:
`cargo run -p gpui --example set_menus`

---

Point to consider:

In `mac/platform.rs:414` the existing code for setting the "Services"
menu remains for backwards compatibility. Should this remain now that
this new method exists to set the menu, or should it be removed?
