Adds `scripts/xlvask-automation-migrate.php` mirroring the existing schema-script pattern (`check` / `apply --yes`), a new AUTOMATION_RUNBOOK §2a documenting both operator entry points, and `XLVaskAutomationMigrateScriptTest` pinning the gate, the WD check, and the bootstrap references.
Production autopilot-runs (POST /modules/xlvask/services/usage/autopilot-runs) was returning 500 with:
```
XL Vask automation schema is not ready. Apply migration 20260804_xlvask_ai_auto_policy_v2 explicitly.
```
because no operator had invoked the gated `applyExplicitMigration()` since PR #348 shipped the migration class. The frontend half of the fix is the companion change in pleno-vue#280 (missing `minimax_integration_enabled` key).
Operator action required once merged:
```
php index.php run xlvask-automation-migrate
# or
php scripts/xlvask-automation-migrate.php apply --yes
```
Both produce identical JSON status; retain the artifact and rerun `check` to confirm postflight is green.
Diff: +140/-0 (3 files). Tests: 87/87 XL Vask unit + 5/5 new migration script test pass.
