fix(build): keep CDN warm discovery route-correct

[james-elicx]

Stacked on #3032.

Summary

• discover normal static child routes whose params are generated by a parent layout
• exclude configured-rewrite public paths from both HTML and canonical RSC warming
• preserve that exclusion when optional locally-prerendered fallback shells are included
• evaluate rewrite sources against the actual trailing-slash warm URL and every configured domain default locale

Scope

Only changes the deploy warm plan. It does not execute rewrites during discovery, locally render pages, alter runtime routing, or expand the deferred special RSC variants.

Validation

• 149 focused discovery, prerender, and Cloudflare warm-plan tests
• targeted vp check on all 6 touched files
• vp run vinext#build
• vp run @vinext/cloudflare#build
