security: scope reusable-workflow secrets (least privilege) over secrets: inherit
The swarm (reviewing the mort/executus rollout PRs) correctly flagged that `secrets: inherit` forwards EVERY caller secret to the reusable review workflow — registry/deploy/db creds the reviewer never touches. Fix: - review-reusable.yml: declare workflow_call.secrets (all optional) so a caller can forward only what the reviewer needs. - adversarial-review.yml (gadfly's own caller) + examples/reusable.yml: replace `secrets: inherit` with an explicit forward of just OLLAMA_CLOUD_API_KEY / CLAUDE_CODE_OAUTH_TOKEN / findings tokens. GITEA_TOKEN stays automatic. - Docs (README, examples) updated; also advise pinning consumers to an immutable @<sha> instead of @main (supply-chain, the other finding). gadfly's own review on this PR exercises the explicit-secrets path (local reusable ref) — validating it on the act_runner before mort/executus adopt it.
