Lately, I've been finding Rust-analyzer unusably slow when editing large
files (like `editor_tests.rs`, or `integration_tests.rs`). When I
profile the Rust-analyzer process, I see that it sometimes saturates up
to 10 cores processing a queue of code actions requests.
Additionally, sometimes when collaborating on large files like these, we
see long delays in propagating buffer operations. I'm still not sure why
this is happening, but whenever I look at the server logs in Datadog, I
see that there are remote `CodeActions` and `DocumentHighlights`
messages being processed that take upwards of 30 seconds. I think what
may be happening is that many such requests are resolving at once, and
the responses are taking up too much of the host's bandwidth.
I think that both of these problems are caused by us sending way too
many code action and document highlight requests to rust-analyzer. This
PR adds a simple debounce between changing selections and making these
requests.
From my local testing, this debounce makes Rust-analyzer *much* more
responsive when moving the cursor around a large file like
`editor_tests.rs`.
Omit in buffers with one or zero running language servers with the

Terminal has to accept `[` and `]` as valid word parts, due to
`[slug].tsx` being a valid file name.
Yet, terminal has to exclude these to match paths in strings like
`[/some/path/[slug].tsx]`.
* Use a single row, instead of centering the search bar within a double-row toolbar.
* Search query controls on the left, navigation on the right
* Semantic is the final mode, for greater stability between buffer and project search.
* Prevent query editor from moving when toggling path filters
Rather than adding primary toolbar item that renders as empty,
don't add an item at all. This prevents spurious spacing from
being added after other primary toolbar items.
See Linear description for the full explanation of the issue. This PR is
mostly a mechanical change, except for the one case where we do pass in
an explicit `next_id` instead of `model_id` in project.rs.
Release Notes:
- Fixed a bug where some results were not reported in project search in
presence of unnamed buffers.
Miltibuffer emits edit events even if it only got an excerpt
added/removed/etc.
Separate buffer edits and trigger hint invalidation refresh for them
only, also trigger hint new lines refresh on excerpt addition events.
