fix(cloudflare): tolerate staged cache propagation

[james-elicx]

Summary

• keep retrying a staged warm request until every independently routed build identity matches
• preserve the existing 60-retry default and explicit --warm-cdn-retries behavior
• retain immediate failure for deterministic validation errors once all stages match

Evidence

The first production deploy after the multi-entrypoint rollout passed probe/readiness, then reached a mixed propagation state where the outer Worker matched while RSC responses still came from the prior stage: https://github.com/cloudflare/vinext/actions/runs/34160828052/job/101863108294

The previous logic stopped retrying as soon as either identity matched. The identical main SHA later warmed all 6/6 entries and promoted successfully once the response stage converged.

Validation

• vp check packages/cloudflare/src/cdn-warm.ts tests/cloudflare-cdn-warm.test.ts tests/cloudflare-cdn-warm-deploy.test.ts
• vp test run tests/cloudflare-cdn-warm.test.ts tests/cloudflare-cdn-warm-deploy.test.ts (130 passed)
