HNSW k-NN fix:
- Search beam width (k) increased from 10 to 100 — previous value
  starved the beam search, causing 0 rows on index scan
- Added ruvector_hnsw_debug() diagnostic function for troubleshooting
- Added warning log when entry_point is InvalidBlockNumber

Hybrid search fix:
- ruvector_hybrid_search() now returns success=true with empty results
  and helpful message on unregistered collections (was success=false)

Audit script fix:
- Corrected hybrid_search argument order in sql-audit-v3.sql Section 9b
- Added HNSW debug diagnostics on 0-row failure

Results: 17 PASS / 0 PARTIAL / 0 FAIL → 100% (up from 88%)
