Impeccable Files

Codex agent delivery simplified. Codex auto-discovers subagents bundled inside an installed skill's own agents/ folder, so skills install and skills update no longer write a separate .codex/agents/*.toml sidecar. The nested in-skill agent is the whole delivery now: one fewer file to install and heal, and nothing left behind in non-Codex projects.

--fast deprecated. Since the jsdom removal the full static scan runs at about 4 ms per file and covers every rule, so the regex-only --fast path only lost coverage (about 10 of 41 rules) for no real speed gain, and a --fast run could read "clean" because most rules silently never ran. The flag is still accepted so existing CI scripts keep working, but it is ignored with a one-line notice and the full scan always runs.
