Claude d571bee394 fix(store): rank multi-filter search REQs + harden merge from branch audit
Two-reviewer adversarial audit of the branch found no correctness/data-loss/
crash bugs. This closes one gap and applies three robustness fixes:

- Multi-filter search ordering: a REQ whose filters all carry a search term
  (e.g. the client's search-across-kinds) was created_at-ordered via the union
  path. Now relevance-ordered — unionSubqueriesIfNeeded(projectRank) projects
  rank per branch, UNION ALL + GROUP BY row_id MIN(rank) dedups across branches
  keeping the best score. Only when every branch is a search branch; mixed
  search/non-search REQs and count/delete unions stay as before.
- prepareAuthorStreams/prepareTagStreams build cursors via buildStreams, which
  closes already-prepared statements if a later prepare throws (was: stranded
  checked-out, un-reset handles holding read locks in the pooled connection).
- Stream counts computed as Long so authors×kinds / values×kinds can't overflow
  Int back into the eligible band and route a huge fan-out into the merge.
- Renamed CachedStatement.finalize() -> finalizeStatement(): a no-arg finalize()
  is the JVM Object.finalize, risking a GC double-close of the native handle.

Tests: multi-filter search relevance + cross-branch dedup + count parity;
existing merge/cache/search suites green.
