fix(cloudflare): reduce staged CDN probe work

[james-elicx]

Summary

• classify each concrete route pathname once and defer alternate HTML/RSC/data representation admission to the final warm render
• use the existing uncapped --warm-cdn-concurrency value for both probing and final warming, keeping that shared pool saturated while preserving late route-resolution safety
• scope middleware-sensitive probe planning to runtime-equivalent matcher semantics, including decoded paths and i18n locale provenance
• route bypass and cacheability-probe renders through a cache-disabled response entrypoint so the gateway never executes renderer code locally
• preserve tag invalidation by routing uncached-render purges through the cache-bearing entrypoint
• preserve Next.js production reload parity by keeping App and Pages responses on the shared host-cache path when a browser sends Cache-Control: no-cache

Validation

• vp check
• vp run vinext#build
• vp run @vinext/cloudflare#build
• 492 cumulative focused App, Pages, Cloudflare Worker, probe, and deploy-flow tests
• deployed Workers Cache E2E now requires App HTML to remain a CF-Cache-Status: HIT under browser no-cache
• previous exact-head CI: 73/73 checks passed before the latest parity fix; refreshed CI is running
• five independent focused reviews clean after requested coverage
• Big Bonk: LGTM before the latest parity fix

Stacked on #3155.
