Marius CiepluchandClaude Fable 5.1 3c36f13e03 feat(pair-corpus-honesty): LLM-generated Real-Vuln repos and unlicensed agent fixes as pointer pairs
Task 8.4 (Req 10.6, 5.1).

- harvest.merge_recipes appends recipes by name and never rewrites
  existing rows.
- vibe-py/build_recipes.py --pointers: the 40 LLM-generated repositories
  without a license become vendored = false rows (80 pairs, agent,
  seeded) appended to recipes.toml; unlicensed human repos stay skipped.
- agent-vfc/build_recipes.py --from ... --pointers [--cache]: unlicensed
  agent-authored fixes become title-tier pointer rows whose function
  label is derived from the cached excerpt (30 added from a fresh
  662-candidate search); TOML booleans rendered correctly.
- catalogs regenerated: vibe-py 115 rows (35 vendored + 80 pointer),
  agent-vfc 59 (29 + 30); no excerpt is vendored for any pointer row.
- `pairs --slice vibe-py --pointers` scores both provenances (human 35,
  agent 80); the default run skips 80 pairs with pointer_pair_skipped;
  suite and gates unchanged. README/docs name the nightly command.

"""Build agent-vfc candidate recipes from agent-authored security-fix commits (maintainer, network via gh).
Candidates come from GitHub commit search on agent co-author trailers or generation
markers plus security-fix wording (see --search). Each candidate is kept only when the
repository states a license, the fix touches one to three JavaScript, TypeScript, or
Python files, and the largest changed file has at most --max-lines changed lines.
Every recipe starts with ``reviewer = "pending"``; a human must set the reviewer and
confirm the mechanism before the pair is trusted (Req 5.3).
