darnit plan --profile still refuses after #597 fixed the reason #709

darnit plan --profile still refuses, and the reason it gives no longer applies.

#576 made darnit audit --profile filter the controls and left plan refusing the flag, because plan crashed on frameworks whose controls carry no level (#568), so the flag couldn't be wired in a way that could be tested on the Baseline. #597 fixed that crash and closed #568.

On main (155dcc1), on jonschlinkert/is-odd:

• darnit plan <repo> exits 0 and prints the plan.
• darnit plan --profile level1_quick <repo> exits 1 with darnit plan does not support --profile yet (#568); use darnit audit --profile, which points at a closed issue.
• darnit audit --profile level1_quick <repo> audits 26 of the 66 controls.

Suggested fix: narrow the plan with _resolve_profile_ids as cmd_audit does, with the same errors for an unknown profile or an empty selection, and remove the refusal and its comment in cmd_plan.
