repo-hygiene: resolve-clean-action consumes only the action token — multi-arg intent (questions, constraints) has no channel

[kyle-sexton]

Problem

/repo-hygiene:clean ALL <multi-line note with a question + live-session constraints> resolves fine to all, but the skill contract defines no handling for the remainder: the user's stash question and "6-7 live sessions, mind WIP" constraint had to be re-derived by the model with no skill support.

Fix direction

Document that trailing args are advisory context the agent must address (cheap), and/or teach the resolver to emit Action: all + Note: <rest> so SKILL.md can direct handling explicitly.
