docs: remove stale distanceSQ8 JSDoc left by the SQ8 hook refactor

The native SQ8 distance hook renamed the original distanceSQ8 to distanceSQ8Js
and added a dispatcher in its place, but left the old function's doc block
orphaned above distanceSQ8Js (two consecutive comments, the first dangling).
Merge them into one accurate block on distanceSQ8Js with dash-notation params.

feat: hook native SQ8 distance provider into HNSW reranking

Makes distanceSQ8 swappable via setSQ8DistanceImplementation and wires brainy.ts to
install a registered 'distance:sq8' provider (e.g. cortex's Rust SIMD), with the JS
distanceSQ8Js as the default fallback. The provider signature is byte-compatible with
the native cosineDistanceSq8, so HNSW SQ8 reranking transparently uses native distance
when cortex is loaded. Native==JS numeric equivalence is asserted by the cross-language
parity suite.

feat: add SQ8 vector quantization, lazy loading, and two-phase rerank to HNSW

- SQ8 scalar quantization (8-bit) for 4x vector storage reduction
- Lazy vector loading: evict float32 vectors after graph construction,
  load on-demand from storage via UnifiedCache
- Two-phase search: over-retrieve with SQ8 approximate distances,
  rerank top candidates with exact float32 distances
- Configuration surface: hnsw.quantization and hnsw.vectorStorage in BrainyConfig
- All features disabled by default (zero behavior change for existing users)
- 27 new tests covering quantization accuracy, lazy loading, reranking
- Remove GitHub Actions CI (build locally, cortex CI handles native builds)
