Marius CiepluchandClaude Fable 5.1 c1621777f9 feat(corpus-seeded-mechanisms): structural variant search merged with overlay flows
Task 2.2 (Req 3.1-3.3, 3.6).

- variants.match_shapes: call sites whose trailing callee name and arity
  match a shape and whose source positions all carry a source of any
  kind; constants and arity mismatches never match.
- semantic/variant_search.py: search_tree over a tree's parsed files with
  the store's corpus shapes (bounded by max_mechanisms, language
  degradations recorded); hits_to_findings merges a hit into an overlay
  promote/coverage record at the same call site (mechanism_id, no
  duplicate) and otherwise emits variant:<id>:<path>:<line> at suspicion
  with the pair provenance in the rationale.
- OverlayRecord.mechanism_id (additive).
