This PR fixes a crash in the fuzzy matcher that occurred when handling
Unicode or multibyte characters (such as Turkish `İ` or `ş`). The issue
was caused by the matcher attempting to index beyond the end of internal
arrays when lowercased Unicode characters expanded into multiple
codepoints, resulting in an out-of-bounds panic.
#### Root Cause
The loop in `recursive_score_match` used an upper bound (`limit`)
derived from `self.last_positions[query_idx]`, which could exceed the
actual length of the arrays being indexed, especially with multibyte
Unicode input.
#### Solution
The fix clamps the loop’s upper bound to the maximum valid index for the
arrays being accessed:
```rust
let max_valid_index = (prefix.len() + path_lowercased.len()).saturating_sub(1);
let safe_limit = limit.min(max_valid_index);
for j in path_idx..=safe_limit { ... }
```
This ensures all indexing is safe and prevents panics.

With the setting `"use_system_path_prompts": false`, previously, if the
completion target was a directory, no separator would be added after it,
requiring us to manually append a `/` or `\`. Now, if the completion
target is a directory, a `/` or `\` will be automatically added. On
Windows, both `/` and `\` are considered valid path separators.

This PR makes progress on #7711 by identifying any common prefix of the
paths in the file finder's search results, and replacing the "interior"
of that prefix---every path segment but the first and last---with `...`,
when a heuristic indicates that the longest path would otherwise
overflow the modal.
The elision is not applied to any segment that contains a match for the
search query.
There may be more work to do on #7711 in the case of long result paths
that do not share a significant common prefix.
Release Notes:
- Improved display of long paths in the file finder modal

* Removes `max_results` from the matcher interface as this is better
dealt with in consumers once all results are known. The current
implementation was quite inefficient as it was using binary search to
find insertion points and then doing an insert which copies the entire
suffix each time.
* There was a corner case where if the binary search found a match
candidate with the same score, it was dropped. Now fixed.
* Uses of `util::extend_sorted` when merging results from worker threads
also repeatedly uses binary search and insertion which copies the entire
suffix. A followup will remove that and its usage.
* Adds `util::truncate_to_bottom_n_sorted_by` which uses quickselect +
sort to efficiently get a sorted count limited result.
* Improves interface of Matcher::match_candidates by providing the match
positions to the build function. This allows for removal of the `Match`
trait. It also fixes a bug where the Match's own Ord wasn't being used,
which seems relevant to PathMatch for cases where scores are the same.

This PR:
- Makes slash commands easier to compose by adding a concept,
`CompletionIntent`. When using `tab` on a completion in the assistant
panel, that completion item will be expanded but the associated command
will not be run. Using `enter` will still either run the completion item
or continue command composition as before.
- Fixes a bug where running `/diagnostics` on a project with no
diagnostics will delete the entire command, rather than rendering an
empty header.
- Improves the autocomplete rendering for files, showing when
directories are selected and re-arranging the results to have the file
name or trailing directory show first.

This fixes a panic in the fuzzy finder which someone ran into when
typing in a query that contained the lower-case version of a unicode
character that has more chars than its upper-case version.
It also fixes another problem which was that we didn't find a match if
both candidates and query contained upper-case characters whose
lower-case version had more chars.
Release Notes:
- Fixed a panic in fuzzy-finder that could occur when matching with
queries containing upper-case unicode characters whose lower-case
version has more chars.
