Task 5.1 (Req 6.1, 6.3).
- reports.py: the markdown and SARIF writers take the mechanisms a run
cites; a finding cites one through its mechanism:<id> tag (variant) or
its merged overlay record's mechanism_id; markdown shows Mechanism,
Known fix guard and Learned from pairs per finding plus a Mechanisms
section, SARIF properties carry mechanism_id/summary/guard/pairs;
variant findings keep suspicion, merged inventory findings keep their
own evidence level; reports without mechanisms are unchanged.
- cli: _search_variants returns the cited mechanisms from the store and
the scan passes them to both writers.
