Add expiration, deletion, and storage reclamation for provisioned sites

[chubes4]

Summary

Adds a generation-bound lifecycle for elastic Cloudflare WordPress allocations with owner controls, grace retention, teardown fencing, bounded reclamation, immutable receipts, and terminal quota release.

What changed

• Adds lifecycle status, renewal, and deletion APIs; fences Worker mutations, operation claims and transitions, publication promotion, imports, and administrator claims; reclaims R2 and D1 work incrementally; records deletion accounting and tombstones.

How to test

1. Run npm run build; expect TypeScript project build succeeds.
2. Run npm run test:cloudflare-runtime; expect Cloudflare runtime, lifecycle race, reclamation, and provisioning suites pass.
3. Run npm run cloudflare:dry-run:d1; expect Wrangler validates the D1 Worker bundle without deployment.

Compatibility

Configured static sites without lifecycle rows retain existing behavior. Existing provisioning authorization, idempotency, and response contracts remain compatible. Anonymous immutable publication reads remain R2-only during grace.
