Resolves part of #34337

Actually I need also to add:

```
"languages": {
    "Vue.js": {
      "language_servers": [
        "vue-language-server",
        "emmet-language-server",
        "..."
      ]
    }
  },
```

not sure how to resolve fully, happy to continue only little guidance
needed.

Release Notes:

- allow emmet in Vue.js files

Previously, this was the one thing that could not be styled properly in
ecmascript languages in the zed config, because it was not able to be
targeted.

Now, it is added alongside other operators. This has been tested and
works as expected.

Closes #34881

For horizontal scroll, we weren't keeping track of the `local` bool, so
whenever the agent tries to autoscroll horizontally, it would be seen as
a user scroll event resulting in unfollow.

Release Notes:

- Fixed an issue where the Follow Agent could unexpectedly stop
following during edits.

This reverts commit efba2cbfd371bdd85dc3bfdd6b98d1d405ad9a89.

Unfortunately, the Docker image for 1.89 has not shown up yet. Once it
has, we should re-land this.

(This PR does not add GPT-5 to Zed Pro, but rather adds access if you're
using your own OpenAI API key.)

/>

---

**NOTE:** If your API key is not through a verified organization, you
may see this error:

<img width="549" height="253" alt="Screenshot 2025-08-07 at 2 04 54 PM"
src="https://github.com/user-attachments/assets/d0b6d739-9c39-4af3-88d7-0c9609b0e6ba"
/>

Even if your org is verified, you still may not have access to GPT-5, in
which case you could see this error:

<img width="543" height="98" alt="Screenshot 2025-08-07 at 2 09 18 PM"
src="https://github.com/user-attachments/assets/e3ed31e3-2a11-4f07-8f3c-5b410fbe4540"
/>

One way to test if you're in this situation is to visit
https://platform.openai.com/chat/edit?models=gpt-5 and see if you get
the same "you don't have access to GPT-5" error on OpenAI's official
playground. It looks like this:

<img width="581" height="196" alt="Screenshot 2025-08-07 at 2 15 25 PM"
src="https://github.com/user-attachments/assets/ea1454ca-3c10-4703-8126-c02cb92a34f2"
/>

Release Notes:

- Added GPT-5, as well as its mini and nano variants. To use this, you
need to have an OpenAI API key configured via the `OPENAI_API_KEY`
environment variable.

When we stop the generation, CC tells us the tool completed, but it was
actually cancelled.

This pull request introduces changes to improve the behavior and
consistency of multiple completion providers
(`CopilotCompletionProvider`, `SupermavenCompletionProvider`) and their
integration with UI elements like menus and inline completion buttons.
It now allows to see the prediction with the completion menu open whilst
pressing `opt` and also enables the subtle/eager setting that was
introduced with zeta.

Edit: I managed to get the preview working with correct icons!

Diagnostics updates were programmed in Zed based off the r-a LSP push
diagnostics, with all related updates happening per file.

https://github.com/zed-industries/zed/pull/19230 and especially
https://github.com/zed-industries/zed/pull/32269 brought in pull
diagnostics that could produce results for thousands files
simultaneously.

It was noted and addressed on the local side in
https://github.com/zed-industries/zed/pull/34022 but the remote side was
still not adjusted properly.

This PR 

* removes redundant diagnostics pull updates on remote clients, as
buffer diagnostics are updated via buffer sync operations separately
* batches all diagnostics-related updates and proto messages, so
multiple diagnostic summaries (per file) could be sent at once,
specifically, 1 (potentially large) diagnostics summary update instead
of N*10^3 small ones.

Buffer updates are still sent per buffer and not updated, as happening
separately and not offending the collab traffic that much.

Release Notes:

- Improved diagnostics performance in the collaborative mode

Now rendering the backdrop behind the card to clean up the UI, bring
focus to the card's content, and direct the user to act on it, either by
ignoring it or upgrading.

Closes #31108

The `num_tokens_from_messages` method we use from `tiktoken-rs` creates
new BPE every time that method is called. This creation of BPE is
expensive as well as has some underlying issue that keeps memory from
releasing once the method is finished, specifically noticeable on Linux.
This leads to a gradual increase in memory every time that method is
called in my case around +50MB on each call. We call this method with
debounce every time user types in Agent Panel to calculate tokens. This
can add up really fast.

This PR lands quick fix, while I/maintainers figure out underlying
issue. See upstream discussion:
https://github.com/zurawiki/tiktoken-rs/issues/39.

Here on fork https://github.com/zed-industries/tiktoken-rs/pull/1,
instead of creating BPE instances every time that method is called, we
use singleton BPE instances instead. So, whatever memory it is holding
on to, at least that is only once per model.
