For inverted diff APIs like `hunks_intersecting_base_text_range`, we
need a snapshot of the main buffer to use as context to compare hunk
anchors, convert anchors to points, etc. Previously, we were always
using a snapshot of the main buffer at the time when the diff was
calculated. This worked well for the hunks of the primary `BufferDiff`,
but it's not valid when the diff also has a secondary set of hunks,
because those hunks are recalculated on their own schedule--so it's
possible for the hunks of the secondary diff to contain anchors that are
newer than the original buffer snapshot that was taken at the time the
primary diff hunks were last calculated. This caused a panic when using
these anchors with the original buffer snapshot.

This PR fixes the issue by using the same approach for inverted diffs as
for non-inverted diffs at the multibuffer level: we take a snapshot of
the main buffer at the time when we snapshot the diff state (including
the diff itself), guaranteeing that that snapshot will be new enough to
resolve all the anchors included in both the primary diff and the
secondary diff.

Closes ZED-54J

Release Notes:

- Fixed a panic that could occur when using the branch diff in split
view mode.

Fixes broken `docs/accounts.html` links in all five migration guides.

## Changes

Replace `https://zed.dev/docs/accounts.html` with
`https://zed.dev/docs/authentication` in:

- `docs/src/migrate/vs-code.md`
- `docs/src/migrate/intellij.md`
- `docs/src/migrate/pycharm.md`
- `docs/src/migrate/webstorm.md`
- `docs/src/migrate/rustrover.md`

These links were flagged as 4xx in an SEO audit. The `accounts.html`
page does not exist; `authentication` is the correct destination.

Release Notes:

After looking around a bit, I felt like subagent wasn't the right way to
introduce this tool to the model. And with some back and forth
verification + market research, we both agreed spawn_agent was a better
name for what this tool is doing.

It still calls the right tool if you ask for a subagent, but especially
if we move these to be running in the background, spawn will be a better
name anyway.

When using the split view, if the project diff inserts excerpts for the
same buffer using two different `PathKey`s, we panic inside
`LhsEditor::update_path_excerpts_from_rhs` because of an implicit
assumption that `excerpts_for_path()` and `excerpts_for_buffer()` return
the same number of values. This PR addresses that by ignoring any
excerpts for the given buffer that have a different path key from the
provided one.

Release Notes:

- Fixed a crash when using the split diff view.

limited the amount of structured data we could send the model.

Now tools can also return structured data in the error cases, which is
super helpful for subagents in particular

- Added a `zed: record etw profile` action that can be used to collect
performance profiles on Windows.

When there is no selection, make `cmd->` (`agent::addSelectionToThread`)
use the current line containing the cursor instead of doing nothing.

Supports both Zed Agent and Zed Assistant.
Works with multiple-cursors and a mix of selections and cursors.

Release Notes:

- Fixed interop detection on WSL not working on newer setups

Looking at this more, the map of tools is just for what is available and
all of the filtering happens at runtime. So we can just rely on the
current behavior for the list of tools (it was already a matching set)
and we can simplify all of the code paths again where we were adding
this filtered list.

When a buffer is folded in the split diff view and then removed from the
multibuffer (via `remove_excerpts_for_path`), the block map's
`folded_buffers` set retains a stale entry for that buffer ID. Later,
when the split view syncs folded state from the RHS display map to the
LHS, it tries to look up the companion mapping for this stale buffer and
fails because the companion no longer tracks a buffer that's been
removed from the multibuffer.

This originally caused a panic via `.expect()`. This PR:

1. Converts the panic into graceful handling by skipping unmapped
buffers.
2. Actively removes stale entries from `folded_buffers` so they don't
persist as ghost state — ensuring that if the same buffer is later
re-added, it won't incorrectly appear as folded.
3. Adds a regression test covering the full lifecycle: fold → remove →
split → re-add → assert both LHS and RHS report the buffer as not
folded.

Release Notes:

- Fixed a crash in split diff view when a folded buffer was removed and
re-added.

The issue I ran into was that responses from anthropic compatible
providers, like Kimi for Coding, have no space after `data:`. This
change just adds a quick check to also allow for those providers to
work.

Before it just resolved but did not show any output:

    },
}
```


TLDR:
- Accepts SSE data:{...} lines (no space) emitted by some alternative
Anthropic providers, in addition to the standard data: {...} format.

Release Notes:

- Fixed Anthropic streaming for alternative providers by accepting SSE data:{...} (no space) lines.

The `unreachable()` assumption at `queue_prediction_refresh` could be
violated by an async race condition:

1. `request_prediction_internal` spawns an async task
2. The task awaits a prediction request
3. If the prediction returns `None`, it calls `queue_prediction_refresh`
4. Between the time the prediction was initiated (when the provider was
an EP-store provider) and when the async callback runs, the user can
change their edit prediction provider setting to a non-EP-store provider
5. `queue_prediction_refresh` re-reads the settings and hits the
`unreachable!()
