fix(cloudflare): require explicit R2 lifecycle replacement rules

[waleedlatif1]

Summary

• Require explicit rules before replacing an R2 bucket lifecycle configuration. Reject missing or blank input while preserving [] to clear rules and populated arrays to replace them.
• Show the required field in both block modes and regenerate metadata and docs with read-first, full-replacement guidance.
• Add request-boundary regressions for absent rules, explicit clearing, and retaining multiple rules. Cloudflare permits omission; this is a deliberate Sim safeguard for replacement intent.

Type of Change

• Bug fix

Testing

Local: bun run lint, root bun run type-check, all 60 check:audits, block-registry checks against origin/staging, and git diff --check passed. Tests run in CI only. Pre-fix CI reproduced exactly the three missing-rules failures; explicit clearing and rule retention passed. Both full unit-test shards passed on the final head in CI, including all 10 Cloudflare request-boundary cases. Remaining build, integration, and E2E gates are reported in this PR’s checks.
