Release Notes:

- Adds UI affordances to the assistant panel to show which messages have
been cached

to be smarter and more selective about when to invalidate the cache and
when to fetch.

I had originally added the lightening bolt on every message and only
added the tooltip warning about editing prior messages on the first
anchor, but thought it looked too busy, so I settled on just annotating
the last anchor.

This PR updates the various GitHub Actions that build Zed binaries to
set the `ZED_CLOUD_PROVIDER_ADDITIONAL_MODELS_JSON` environment variable
from the corresponding secret.

Release Notes:

- Clicking on an already-deployed popover menu trigger now hides the
popover menu.

This fixes a weird bug:

1. Use `/workflow` in assistant
2. Have it generate a step that modifies a file
3. Either (a) select the step in the assistant and have it auto-insert
newlines (b) select "Transform" to have the step applied
4. Close the modified file in the editor ("Discard")
5. Re-open the file
6. BUG: the changes made by assistant are still there!

The reason for the bug is that the assistant keeps references to buffers
and they're not closed/reloaded when closed/reopened.

To fix the bug we now rollback the applied workflow steps when
discarding a buffer.

(This does *not* yet fix the issue where a workflow step inserts a new
buffer into the project/worktree that does not show up on the file
system yet but in `/file` and hangs around until Zed is closed.)

This PR adds the `is_staff` field to the `upstream rate limit` spans.

Since we use different API keys for staff vs non-staff, it will be
useful to break down the rate limits accordingly.

That way, user can click on "Transform" straight away and get it applied
immediately when it's resolved.

This makes it easier to debug why resetting a key doesn't work. We now
show when the key is set via an env var and if so, we disable the
reset-key button and instead give instructions.

This commit adds a custom icon for Anthropic hosted models.

- Adding a new SVG icon for Anthropic hosted models.
  - The new icon is located at: `assets/icons/ai_anthropic_hosted.svg`
- Updating the LanguageModel trait to include an optional icon method
- Implementing the icon method for CloudModel to return the custom icon
for Anthropic hosted models
- Updating the UI components to use the model-specific icon when
available
- Adding a new IconName variant for the Anthropic hosted icon

We should change the non-hosted icon in some small way to distinguish it
from the hosted version. I duplicated the path for now so we can
hopefully add it for the next release.

I want to showcase Zed's performance via videos, and this seemed like a
good way to demonstrate it.


https://github.com/user-attachments/assets/f4a5fabc-efe7-4b48-9ba5-719882fdc856

Release Notes:

- On macOS, you can now set assign `performance.show_in_status_bar:
true` in your settings to show the time to the first window draw on
startup and then current FPS of the containing window's renderer.

Release Notes:

- Fixed an issue where an extra newline was inserted after running a
`/file` command in the assistant.

When launching Zed from the CLI via `cargo run`, we'll always prompt
load templates from the repo.

This restores behavior that I reverted last night in #16403.

Also, I've improved the `script/prompts link/unlink` workflow for
overriding prompts of your production copy of Zed. Zed now detects when
the overrides directory is created or removed, and does the right thing.
You can link and unlink repeatedly without restarting Zed.

The original idea was for the keybinding to be within the description, but given it's already inline with the title, I figure we don't need this anymore—cleaning it up a bit!

This PR reverts #16145 and subsequent changes.

This reverts commit a515442a365229155cde3de946e1b3eb244c0d36.

We still have issues with our approach to indentation in Python
unfortunately, but this feels like a safer equilibrium than where we
were.
