Acceptance: fixture-plan heal probe (north star)

Part of plans/ledger-coordinate-migration — the generic, plan-agnostic on-serve coordinate heal.

Items

• w-ca699b40 — Author the north-star acceptance probe in scripts/heal_ledger_coordinates_runtime/tests/test_acceptance.py: drive serve -> dispatch -> classify -> persist -> re-scan on the fixture plan; assert migration_coverage(fixture).unmigrated_in_range == 0 AND the bootstrap case is covered.
• w-e9610d4a — Author the gate + dispatch unit matrix: coordinate_heal_target over {bootstrap, incremental, covered, no-opt-in}; the sentinel TTL at-most-once semantics; and the plan-agnostic guard (a plan declaring no taxonomies yields target=None and emits no dispatch).
