fix(core): HNSW correctness fixes, k=0 guard, sorted results, cross-integration helpers (v2.2.3) (#502) 
* fix(core): correctness + safety fixes in HNSW/flat index + cross-integration helpers (v2.2.3)

Correctness fixes:
- hnsw: `DistanceFn::eval` now clamps distance to 0.0 — prevents hnsw_rs
  internal BinaryHeap assertion panic when floating-point rounding yields a
  marginally-negative cosine/euclidean distance for near-identical vectors
- hnsw: `set_ef_search` was a silent no-op; now correctly writes to
  `config.ef_search` so callers can tune recall at query time
- hnsw: `search_with_ef` clamps `ef_search` to `max(ef_search, k)` to
  prevent silent under-recall when ef_search < k (hnsw_rs constraint)
- hnsw: `search_with_ef` now explicitly returns an empty slice for k=0
  instead of forwarding to hnsw_rs which may panic
- hnsw: `search_with_ef` returns early (empty slice) when index is empty
  to avoid hnsw_rs BinaryHeap `.peek().unwrap()` panic on zero-element index
- hnsw: results are now explicitly sorted by ascending distance; hnsw_rs
  does not guarantee this order in all code paths
- hnsw: deserialization rebuilds the HNSW graph in index order
  (sorted by idx) and uses an O(n) HashMap lookup instead of O(n^2)
  linear search over the vectors vec during restore
- flat: added k=0 guard (returns empty slice, no panic)
- flat: switched sort to `sort_unstable_by` with a `partial_cmp` fallback
  to handle NaN distances gracefully and improve throughput on large sets

API improvement:
- types: `HnswConfig::default()` now uses `max_elements=1_000_000` (was
  10_000_000) and `m=16/ef_construction=100` to avoid excessive upfront
  memory allocation in the common case; large-index callers can still
  set `max_elements` explicitly

New module:
- integration: `FannAdapter` and `SemanticSearchAdapter` — thin wrappers
  that make ruvector-core directly usable from ruv-FANN (layer-embedding
  storage + retrieval) and sparc (semantic file search by embedding query).
  Includes `normalize()` and `cosine_similarity()` free-standing utilities.

Tests (4 new integration, 3 new unit):
- test_hnsw_search_k_zero: k=0 returns empty, no panic
- test_hnsw_results_sorted_ascending: verifies window[i].score <= window[i+1].score
- test_hnsw_set_ef_search_updates_config: set_ef_search writes through to config
- test_hnsw_search_with_ef_clamps_to_k: ef < k still returns results
- flat: test_flat_index_k_zero, test_flat_index_results_sorted
- integration: FannAdapter and SemanticSearchAdapter roundtrip tests

Version bump: 2.2.2 → 2.2.3
