ChromaSync.queryChroma() returns deduplicated sqlite_ids but the
metadatas array contains multiple entries per observation (narrative +
facts). The filterByRecency() method was iterating over metadatas and
using the index to access ids, causing array out-of-bounds access.
The fix builds a Map from sqlite_id to metadata, then iterates over
the deduplicated ids array to ensure proper alignment.
Symptoms before fix:
- Semantic search returning incorrect/empty results
- Search only working with near-exact queries
- Recent items (same day) not being found
