Jiayuan Zhang 02cdfcb93f feat(search): improve ranking with ILIKE, identifier search, multi-word support (#601)
* feat(search): improve ranking with ILIKE, identifier search, multi-word support

- Replace LIKE with ILIKE for case-insensitive matching
- Support identifier search (e.g. "MUL-123" or bare "123")
- Refine sorting tiers: number match > exact title > title starts with >
  title contains > all words in title > description > comment
- Add status-based tiebreaker (active issues rank higher)
- Support multi-word search where all terms must match somewhere
- Move search query from sqlc to dynamic SQL for flexibility

* fix(search): fix parameter type error for single-word queries

Only allocate per-term SQL parameters when there are multiple search
terms. For single-word queries, the phrase parameter already covers
the search — unused term params caused PostgreSQL error
"could not determine data type of parameter $3".
