fix(kyberforge): resolve PR #144 review and audit round 3

- factory-audit: hook events judged per deployed target after apm's
  rename (Claude/Copilot event sets FAIL, others SUGGESTION); Claude
  plugin layouts accepted as hook sources; interpreter options and
  sh -c strings checked; bats 378 -> 386
- primitive-author: Must 4/5 match the audit; reference hand-back
  points at the right steps; Step 4.2 --target all fallback
- skill-author: new-skill.sh repair only on the template marker line,

- forge: restore "already named" qualifier; drop false HITL claim
- apm-workflow: token example uses an env var
- docs/hooks.md: the apm-hooks.json sidecar is committed, not ignored
