## Title

    Proposed fix: [Cloudflare Durable Objects] Lifecycle changes via 'exports' (or legacy migrations) cannot be applied by 'wrangler versions upload' / gradual deploys; exports and migrations are mutually

## Body

    Recommended action: Apply DO class lifecycle changes only with wrangler deploy (not versions upload/gradual), choose exports or legacy migrations (not both), and plan renames as multi-deploy sequences; to change storage backend delete and re-provision.
    
    Option: Use wrangler deploy for DO lifecycle changes [evidence: official_recommended_action]
    Applies when: Adding/renaming/deleting DO classes
    Steps:
    1. make lifecycle change in exports (or migrations) only
    2. wrangler deploy
    3. use versions upload/gradual only for code-only changes
    Expected: Lifecycle reconciled
