ykiko	005fc9ac21	feat(index): optimize merge with ContextBitmap, hash caching, and selective merge ... Introduce ContextBitmap (tagged-pointer inline bitmap for <63 ids) to replace roaring::Roaring in MergedIndex hot paths, eliminating heap allocations in the common case. Cache FileIndex SHA256 hashes to avoid recomputation. Add selective ProjectIndex::merge that skips symbols not referencing newly-merged files. MergedIndex::merge now returns bool to indicate cache hits. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-04-18 14:49:39 +08:00
