feat: add is:broken search qualifier for broken links (#2225)

Add a new search qualifier `is:broken` that allows users to filter bookmarks
with broken or failed links. This matches the functionality on the broken links
settings page, where a link is considered broken if:
- crawlStatus is "failure"
- crawlStatusCode is less than 200
- crawlStatusCode is greater than 299

The qualifier supports negation with `-is:broken` to find working links.

Changes:
- Add brokenLinks matcher type definition
- Update search query parser to handle is:broken qualifier
- Implement query execution logic for broken links filtering
- Add autocomplete support with translations
- Add parser tests
- Update search query language documentation
