safishamsiandClaude Opus 4.8 7a9cda2452 fix(cache): prune orphan semantic-cache entries at end of extract (#1527)
The AST cache is version-swept but the semantic/LLM cache had no pruning,
so it grew unbounded: it is content-hash-keyed, so every content change
or file deletion leaves a permanent orphan entry (reporter saw 152
entries for 124 live docs). This matters for the committed-cache workflow
where the semantic cache is published for warm CI rebuilds.

Adds prune_semantic_cache(root, live_hashes) and wires it into the end of
the extract path, sweeping cache/semantic/*.json entries whose hash is not
in the live set. The live set is computed from the FULL detected document
set (not the incremental changed-subset, which would delete valid
entries), using the same file_hash recipe save_semantic_cache uses.
Best-effort (unlink guarded), only touches cache/semantic/ (.tmp and
cache/ast/** untouched), and keeps the semantic cache unversioned so
releases never re-bill LLM extraction.
