self-check: drop /autotask from baseline commands

/autotask exists nowhere as a Claude command (no .claude/commands/autotask.md in
the repo; only a Grok skill by that name). It was a GURU-5070-specific artifact in
the provisional manifest and produced a spurious RED on every other machine. Removing
it clears the false FAIL fleet-wide.
