feat: add GitHub security posture checks

Deepen the GitHub audit with five new collectors:

- org_security: org settings (2FA requirement, default permission, repo
  creation, secret-scanning defaults).
- webhooks: org and per-repo webhooks, flagging plain-HTTP delivery and disabled
  SSL verification.
- deploy_keys: deploy keys across all repos (read-only vs read-write).
- secret_scanning / dependabot_alerts: open Advanced Security alerts; skip
  gracefully (403/404) when GHAS or permissions are unavailable, off by default.

Wire them into github_runner and audit.py, add mocked-HTTP unit tests for the
new collectors (the first collector-level tests for GitHub), and update the
README scope/permission notes.

-> - Organization: Administration (read), Members (read)
+> - Organization: Administration (read), Members (read), Webhooks (read)
+> - Secret scanning and Dependabot alerts require GitHub Advanced Security and

 > - Audit log collection also requires GitHub Enterprise Cloud. Classic PATs need
