fix: clean-lens findings + trim the dogfood swarm to strong reviewers (#4)

emit() now skips findings extraction for a "No material issues found"
lens (its path:line refs are verification notes, not problems), fixing
the FP inflation that penalized thorough clean-pass reviewers. Also trims
the dogfood swarm to the strong reviewers: drops m5/qwen3.6 (last local
lane), gemma4, gpt-oss:120b, and kimi-k2.7-code — leaving 6 cloud +
claude-code/sonnet.

Fittingly, PR #4's own 11-model review produced 43 findings that were ALL
clean-verification bullets (zero real) — a live demonstration of the bug
this fixes. gofmt clean, go vet quiet, go test -race green.
