chore(claude-do): Normalize list ID format

list_task_lists returns two different ID formats: dashed UUIDs (e.g. "caed660e-109f-4e2a-b055-2c2722bf6fb7") and compact 32-char hex (e.g. "5c2cafcb33f044069ac324ac3fd84a16"). Mixing formats makes equality checks, logging, and lookups error-prone.

Fix: pick one canonical format (recommend dashed UUID) and normalize on write + migrate existing records. Ensure all ID-returning tools emit the same f
