Closes https://github.com/zed-industries/zed/issues/38643

This PR adds some UI improvements to the Zed replacement of the system
dialog/prompt, including better visibility of which button is currently
focused.

One little design note, though: because of a current (and somewhat
annoying) constraint of button component, where we're only drawing a
border when its style is outlined, if I kept them horizontally stacked,
there'd be a little layout shift now that I'm toggling styles for better
focus visibility. So, for this reason, I changed them to be vertically
stacked, which matches the macOS design and avoids this problem. Maybe
in the future, we'll revert it back to being `flex_row` because that
ultimately consumes less space.

Release Notes:

- xAI: Added support for for configuring tool and image support for

Since we might run MCP servers locally for an agent, we don't want to
use the proxy for those.
We set this if the user has set a proxy, but not a custom NO_PROXY env
var.

# Why

# How

I have also remove manual `max-width` setting since it is controlled by
flex layout and gap setting no matter if there is an additional element
on the right or not.

The edit prediction button menu was displaying stale authentication
status due to capturing the Copilot status in a closure. After signing
out, the menu would still show "Sign Out" instead of "Sign In to
Copilot".

This change fixes the issue by reading the current Copilot status each
time the menu is displayed, ensuring the menu options are always
accurate.

i'm testing out zed, coming from emacs, and so i'm trying out the base
keymap for it. i noticed though that zed's default git keybindings don't
work when the gitpanel is open though, because of the top-level binding
of `ctrl-g` to cancel. my expectation is that the emacs-like keybindings
would work insofar as they don't clobber zed's defaults (which would
take precedence), but obviously i'll defer to others on this!

another option could be to use the `C-x v` keymap prefix that the emacs
built-in `vc` package uses, but it doesn't contain the same set of
bindings for git commands that zed has.

This reverts commit 1bbf98aea6f335e791f19d8f76ba8a5f0510937f.

We found that #38411 caused problems where anonymous functions are
included too many times in the outline. We'd like to figure out a better
fix before shipping this to stable.

Fixes #38956

Release Notes:

- (preview only) revert changes to outline view

When working on the PR above I have spotted that keybinding to text
helpers incorrectly detects if Vim mode is enabled.

# How

Replace inline check with an existing `KeyBinding::is_vim_mode` method
in keybinding text helpers.

Release Notes:

- Fixed incorrect Vim mode detection in UI keybinding to text helpers.

# Test plan

Made sure that when Vim mode is not specified in settings file it
resolves to `false`, and correct keybindings are displayed, than I have
added the `"vim_mode": true,` line to my settings file and made sure
that keybindings text have changed accordingly.

Closes #ISSUE

Improves the efficiency of our interactions with the Zed language
server. Previously, on startup and after every workspace configuration
changed notification, we would send >1MB of JSON Schemas to the JSON
LSP. The only reason this had to happen was due to the case where an
extension was installed that would result in a change to the JSON schema
for settings (i.e. added language, theme, etc).

This PR changes the behavior to use the URI LSP extensions of
`vscode-json-language-server` in order to send the server URI's that it
can then use to fetch the schemas as needed (i.e. the settings schema is
only generated and sent when `settings.json` is opened. This brings the
JSON we send to on startup and after every workspace configuration
changed notification down to a couple of KB.

Additionally, using another LSP extension request we can notify the
server when a schema has changed using the URI as a key, so we no longer
have to send a workspace configuration changed notification, and the
schema contents will only be re-requested and regenerated if the schema
is in use.

Release Notes:

- Improved the efficiency of communication with the builtin JSON LSP.
JSON Schemas are no longer sent to the JSON language server in their
full form. If you wish to view a builtin JSON schema in the language
server info tab of the language server logs (`dev: open language server
logs`), you must now use the `editor: open url` action with your cursor
over the URL that is sent to the server.
- Made it so that Zed urls (`zed://...`) are resolved locally when
opened within the editor instead of being resolved through the OS. Users
who could not previously open `zed://*` URLs in the editor can now do so
by pasting the link into a buffer and using the `editor: open url`
action (please open an issue if this is the case for you!).
