Merged into release/v3.8.45. CI merge-integrity fast-gates (changelog-integrity + agent-skills-sync) + pre-flight hermetic mode. O gate novo detectou 11 SKILL.md gerados fora de sync (drift pré-existente no tip: omni-api-keys endpoints, omni-github-skills do #6186) — regenerados neste PR, Merge-integrity GREEN no CI. Reds restantes base-red (dast-smoke/file-size drift/live-data flaky). Testes novos 17/17.
PR #6186 added omni-github-skills to the agent-skills catalog (API 22 -> 23)
but did not run the generator, so skills/omni-github-skills/SKILL.md never
existed and 6 integration assertions split between the old (42/43) and new
counts. Generated via scripts/skills/generate-agent-skills.mjs --apply and
aligned agent-skills-discovery to the real totals (43 = 23 API + 20 CLI;
handlers return 44 with config-codex-cli). 30/30 discovery+content tests green.
