Re-land of #20515 with less brokenness

In particular it turns out that for control, the .characters() method
returns the control code. This mostly didn't make a difference, except
when the control code matched tab/enter/escape (for
ctrl-y,ctrl-[/ctrl-c) as we interpreted the key incorrectly.

Secondly, we were setting IME key too aggressively. This led to (in vim
mode) cmd-shift-{ being interpreted as [, so vim would wait for a second
[ before letting you change tab.

With this PR, Git status is now the only thing that can change an item's
label color. So, the summary of how status colors operate in the project
panel is:

- Item icon color is, by default, never changed, _not_ affected by
either diagnostics or Git status
  - This should become configurable in the near future, though
- However, a little x or triangle icon shows up on top of the file type
icon to display diagnostics status
- Label color is _not_ affected by diagnostics but it _is_ affected by
Git status

This aims to reduce color noise and clarify/simplify how each element is
affected.

This PR extracts the `ExtensionIndexedDocsProvider` implementation to
the `indexed_docs` crate.

To achieve this, we introduce a new `Extension` trait that provides an
abstracted interface for calling an extension. This trait resides in the
`extension` crate, which has minimal dependencies and can be depended on
by other crates, like `indexed_docs`.

We're then able to implement the `ExtensionIndexedDocsProvider` without
having any knowledge of the Wasm-specific internals of the extension
system.

Closes #19227

Since items listed in `.gitignore` file are not included in a worktree,
python virtual environment cannot be detected until venv directory is
unfolded from project panel and forcefully added into worktree. I didn't
come up with anything better than scanning fs directly. I'm not sure how
it will affect remote development. if at all.

Release Notes:

- Fixed detection of `detect_venv.directories` ignored by a worktree

This is a follow-up (or related to) #20412.

It fixes entries being marked when navigating between tabs with `cmd-[`
and `cmd-]`.

Turns out that deep in the bowels of the project panel, we check whether
a `shift` modifier was pressed - which is the case with `cmd-[` on a US
ANSI layout - and if so mark an entry.

I think that's a left-over, because all the other code paths that
select/reveal an entry mark it explicitly too.

Release Notes:

- Fixed entries in project panel being marked when navigating between
tabs with keybinding that uses `shift` modifier.

Release Notes:

- Improved task tabs to always rerun tasks on click

- Making sure this design and properties are the same across different
places
- No need for the `ButtonLike` here, we can use `Button` as it supports
`key_binding` and makes it for a cleaner code!
- Also, that ensures the binding is always to the right of the label,
which makes more sense
- Title-case the labels for consistency with other buttons across the
app

This reverts commit https://github.com/zed-industries/zed/pull/20515

I'm reverting for now to fix issues with key bindings on Nightly:
* `ctrl-c` and `ctrl-m` are being treated as `ctrl-enter`
* `ctrl-[` isn't working in vim mode
* there's a delay before `cmd-shift-[` switches tabs w/ vim mode enabled

This upgrades `nbformat` and `runtimelib` to handle jupyter types with
even more validation and flexiblity. This also processes any multiline
string data coming from the kernel, including with image data (like
`image/png`). While I was at it I also fixed a longstanding issue around
images by eliminating all whitespace (something `atob` does) and using
the no pad decoder.

This PR exposes context server settings to extensions.

Extensions can use `ContextServerSettings::for_project` to get the
context server settings for the current project.

The `experimental.context_servers` setting has been removed and replaced
with the `context_servers` setting (which is now an object instead of an
array).

This change refactors how we handle input on macOS to avoid simulating
our own IME. This fixes a number of small edge-cases, and also lets us
remove a bunch of code that had been added to work around bugs in the
previous version.

Release Notes:

- On macOS: Keyboard shortcuts are now handled before activating the IME
system, this enables using vim's default mode on keyboards that use IME
menus (like Japanese).
- On macOS: Improvements to handling of dead-keys. For example when
typing `""` on a Brazillian keyboard, you now get a committed " and a
new marked ", as happens in other apps. Also, you can now type cmd-^ on
an AZERTY keyboard for indent; and ^ on a QWERTZ keyboard now goes to
the beginning of line in vim normal mode, or `d i "` no requires no
space to delete within quotes on Brazilian keyboards (though `d f "
space` is still required as `f` relies on the input handler, not a
binding).
- On macOS: In the terminal pane, holding down a key will now repeat
that key (as happens in iTerm2) instead of opening the character
selector.

This PR creates a new, revamped `DecoratedIcon` component that enables
using different SVGs, one for the knockout background and another for
the actual icon. That's different than what we were doing before—copying
the SVG and using slightly different positioning—because we wanted to
unlock an aligned knockout effect, which was particularly hard to do
with non-simple shapes such as an X.

This PR adds initial support for FreeBSD
(https://github.com/zed-industries/zed/issues/15309). While there is
still work left to be done, it seems to be usable. As discussed by
@syobocat (https://github.com/zed-industries/zed/discussions/10247), the
changes were just adding ```target_os = "freebsd"``` to wherever it
checks if the OS is Linux.


![image](https://github.com/user-attachments/assets/80ea5b29-047f-4cbd-8263-42e5fa6c94b7)

Needs to be build with ```RUSTFLAGS="-C link-dead-code"```

Known Issues:
- There's an issue in ```crates/project/src/environment.rs``` where a
command fails because ```/bin/sh``` on FreeBSD doesn't support the
```-l``` option.

![image](https://github.com/user-attachments/assets/c3c38633-160f-4f47-8840-e3da67f6ebc8)
- The file/folder choosers provided by the ```ashpd``` crate don't work
on FreeBSD (at least with KDE). This isn't that bad since a fallback
dialog is used.

![image](https://github.com/user-attachments/assets/29373006-1eb9-4ed0-bd52-2d0047fab418)
 - Moving to trash won't work.
- Numerous tests fail (when running on FreeBSD). While I haven't looked
into this much, it appears that the corresponding features seem to work
fine.

- Added initial support for FreeBSD

      "inline_completions_disabled_in": ["comment", "string"]
    }
  }
}
```

```json
{
  "inline_completions_disabled_in": ["comment"]
}
```

Closes #9133

Release Notes:

- Added language setting to disable inline comments in certain scopes.

Density tracking issue: #18078 

This PR refactors our spacing system to use a more flexible and
maintainable approach. We've replaced the static `Spacing` enum with a
dynamically generated `DynamicSpacing` enum using a proc macro.

Enum variants now use a `BaseXX` format, where XX = the pixel value @
default rem size and the default UI density.

For example:

`CustomSpacing::Base16` would return 16px at the default UI scale &
density.

I'd love to find another name other than `Base` that is clear (to avoid
base_10, etc confusion), let me know if you have any ideas!

Changes:

- Introduced a new `derive_dynamic_spacing` proc macro to generate the
`DynamicSpacing` enum
- Updated all usages of `Spacing` to use the new `DynamicSpacing`
- Removed the `custom_spacing` function, mapping previous usages to
appropriate `DynamicSpacing` variants
- Improved documentation and type safety for spacing values

New usage example:

```rust
.child(
    div()
        .flex()
        .flex_none()
        .m(DynamicSpacing::Base04.px(cx))
        .size(DynamicSpacing::Base16.rems(cx))
        .children(icon),
)
```

vs old usage example:

```
.child(
    div()
        .flex()
        .flex_none()
        .m(Spacing::Small.px(cx))
        .size(custom_spacing(px(16.)))
        .children(icon),
)
```

Closes #20476

Release Notes:

- Fixed a bug in toolchain selector that caused it to not pick up venvs
for tabs before user interacted with them.
- Fixed a bug in language selector that caused it to pick up Markdown as
the language for a buffer up until the tab was interacted with.

This fixes the language server log menu only showing a single entry when
using SSH remoting.

Culprit was the `return menu;` statement that should've been a
`continue;`

Rest of the change is just refactoring.

Release Notes:

- Fixed `language server logs` menu only showing a single entry when
using SSH remoting.

This fixes the issue of multiple language servers showing up as `node`
in the language server logs dropdown.

It does this by changing `language_server.name()` to return the
adapter's name, not the binary name, and changing types to make sure
that we always use this.

Release Notes:

- Fixed language server names showing up only as `"node"`
