fix(cloudflare): warm the deployed Worker route host

[james-elicx]

Summary

• derive the CDN warmup origin from the concrete catch-all Worker route reported by wrangler triggers deploy
• prefer that exact deployed route over workers.dev fallback, including workers_dev: false, singular route, and { pattern, zone_name } route objects
• preserve the declared HTTP/HTTPS scheme, reject wildcard or path-scoped routes that cannot provide one canonical site-wide warmup origin
• do not infer warmup hosts from TPR's zone-oriented Wrangler config parser
• describe Workers Caching tiered propagation accurately in deploy help
• align the deploy-flow assertion with the preceding deterministic retry policy (no runtime retry change here)

This is stacked on #3034 and remains limited to RSC/HTML CDN prewarming target correctness. It does not change TPR or add Wrangler TOML parsing.

Validation

• vp test run tests/deploy.test.ts tests/cloudflare-cdn-warm-deploy.test.ts (345 passed)
• vp check packages/cloudflare/src/deploy-help.ts packages/cloudflare/src/deploy.ts packages/cloudflare/src/version-deploy.ts packages/cloudflare/src/worker-deployment-url.ts tests/cloudflare-cdn-warm-deploy.test.ts tests/deploy.test.ts
• vp run vinext#build
• vp run @vinext/cloudflare#build

Documentation checked

• Cloudflare Workers route configuration and matching behavior
• Wrangler 4.80 config schema for route, routes, pattern, and zone_name
• Cloudflare Workers Caching tiered-cache behavior
