This PR fixes a panic that could occur when trying to complete arguments
for the `/delta` slash command.

We were using `unimplemented!()` instead of providing a default no-op
implementation like we do for other slash commands that do not support
completing arguments.

Closes https://github.com/zed-industries/zed/issues/19686.

Release Notes:

- Fixed a panic that could occur when trying to complete arguments with
the `/delta` command.

- Closes: https://github.com/zed-industries/zed/issues/19609

Switches us to using `-latest` tags with Anthropic models instead of
pinning to a specific date version.
See: [Anthropic Model
Docs](https://docs.anthropic.com/en/docs/about-claude/models)

This is a no-op for:
- Claude 3 Opus (`claude-3-opus-20240229`)
- Claude 3 Sonnet (`claude-3-sonnet-20240229`)
- Claude 3 Haiku (`claude-3-haiku-20240307`)

For Claude 3.5 Sonnet this will update us from
`claude-3-5-sonnet-20240620` to `claude-3-5-sonnet-20241022`. We will
also pickup any subsequent model updates automatically when Anthropic
updates the `latest` tag.

This matches the behavior for OpenAI where use `gpt-4o` as the
model_name and not `gpt-4o-2024-08-06`.

Before this change we had a race condition bug: if stderr was closed
before the other two sockets, we wouldn't properly detect when the
server died, and not report or retry anything.

That's because we treated a closed stderr as a non-error.

Technically, it isn't an error (closing a connection is okay!), but
until we have a proper shutdown ceremony between all three processes, we
can treat it as an error, because that lets us to detect when the server
is gone.

On the client-side, we also always react to these errors by
reconnecting. Except when we shutdown: there we do a proper shutdown and
won't error on the proxy exit code.

So, this works, even if I wish there was a better way for the server to
communicate to the proxy that it shutdown properly. But I don't want a
fourth socket.

This PR makes it so collab will trigger a refresh for a user's LLM token
whenever their subscription changes.

This allows us to proactively push down changes to their subscription.

In order to facilitate this, the Stripe event processing has been moved
from the `api` service to the `collab` service in order to access the
RPC server.

I've been a bit annoyed by the hover divider rule being extremely bright
compared to other divider rules in the UI. This PR updates their color
to use the regular border color from the current theme instead of the
muted (but still pretty bright) text color.

Apologies for the unsolicited PR (and please feel free to close if it
goes against some other plans / designs you already have in place :).

Reverts zed-industries/zed#17756. According to the existing
implementations of the LSP specification, namely
[Helix](https://github.com/helix-editor/helix/blob/a7651f5bf027ec98645d571ab05a685d97e1b772/helix-view/src/document.rs#L1038)
and, if I'm not wrong,
[VSCode](https://github.com/microsoft/vscode-languageserver-node/blob/main/client/src/common/textSynchronization.ts#L580),
`textDocument/didSave` has nothing to do with the watched files and
should be sent to the language servers connected to the buffers even if
the files are not watched by those. As the LSP spec doesn't say anything
about `didSave` being related to the watched files, and the reference
implementation in VSCode seemingly does not filter the notifications
according to those, it seems like this is an incorrect interpretation of
the specification

This also causes issues with language servers. See [Metals
issue](https://github.com/scalameta/metals-zed/issues/28#issuecomment-2410393150)
for example

Closes #19040
Addresses the problem with annoying error messages on windows (see
comment from SomeoneToIgnore on #18567)

Release Notes:

- Fixed the bug where language servers from PATH would sometimes be
prioritised over the ones from `direnv`
- Stopped running environment loading on windows as it didn't work
anyways due to `SHELL` not being set

This commit adds support for using the physical insert-button. First
click toggles insert mode and subsequent clicks toggle back and forth
between replace and insert mode.

Closes #19224

Release Notes:

- Added support for using the insert button for vim_mode.

Part of https://github.com/zed-industries/zed/issues/19239

Overall, this hardcoding approach has to stop and Zed better show some
notification/modal that proposes to select a primary language server,
when launching with the language that has no such settings.

Release Notes:

- Fixed Astro LSP interactions

This PR refines the SSH modal UI, adjusting spacing and alignment. Via
these changes, I'm also introducing the ability for the `empty_message`
on the `List` component to receive not just a string but any element.
The custom way in which the SSH modal was designed made it feel like
this was needed for proper spacing.

Sometimes, issues are created outside of issue templates (which we don't
prefer, but we can't prevent). This updates our top-ranking issues
script such that it will add `triage` and `admin read` labels to any

when doing the next triage.

This does two things.

Important one: it reverts #19193, which lead to our whole process
handling breaking. When the `proxy` process was killed, it apparently
didn't close the stdout/stderr anymore, which meant we would not detect
when it died. (Watching its `status()` in the io loop also didn't work!)

We should figure out how to keep our process handling working before we
make this change in #19193, which sounds reasonable.

Second, less important thing: I think we should treat the process being
killed from a signal as non-zero, as an error.

This improves the heartbeat detection logic. We now treat any other
incoming message from the ssh remote server
as a heartbeat message, meaning that we can detect re-connects earlier.

It also changes the connection handling to await futures detached.

TL;DR: Another O(n^2) strikes.

In #19194 we received a report about a 7Mb JSON file that Zed struggles
with. Naturally this file showcased a O(n^2) in line layout; this file
has one long line.

During line layout for Mac we have to convert between UTF-16 and UTF-8
indices in the string, as CoreText works with UTF-16 and Rust strings
are UTF-8. The problem stemmed from the fact that we were re-seeking our
string converter on each glyph, which boils down to: we were reparsing
[0..curr_string_position] bytes up to full length of the string, which
is the O(n^2) in question. This PR changes this behaviour to reuse the
Index Converter if the position we're seeking to is not yet reached.
Basically, we're treating the converter as forward iterator and we try
to seek with the same iterator, if possible.

Where previously you could not even open the file in OP (within
reasonable time frame, I waited for 40 seconds before giving up), now
you can do it in.. slightly over a second. The best part is: the
experience is still not ideal. Typing in the buffer is sluggish. Still,
this is a start.

- Mac: Improved performance with very long lines
