feat(workflows): add drill-deck-review + extend drill-to-anki script

I added a drill-deck-review workflow that walks an org-drill deck end-to-end: question-form audit on every heading (so the heading is the prompt, not the answer), content-accuracy audit via subagent against project source-of-truth, source rewrite preserving SRS state, regenerate to ~/sync/phone/anki/. The workflow covers three card families (acronym/concept, person, talking-point) and codifies the person-card pattern as "Who is X? Tell me about their Y." where X is a role descriptor that doesn't name the person and Y is the topical anchor from the answer body.

The drill-to-anki.py script picks up a new strip_org_metadata helper that drops :PROPERTIES: drawers and SCHEDULED/DEADLINE/CLOSED planning lines from the rendered Anki back. Org-drill needs both in the source for SRS state and review scheduling; Anki cards shouldn't show them.

INDEX entry under "On-demand utilities" wires the trigger phrases.
