fix(build): exclude route handlers from CDN warm paths

[james-elicx]

Summary

• apply runtime App/Pages ownership resolution to HTML warm paths as well as RSC paths
• exclude concrete App candidates shadowed by App route handlers or Pages API routes
• retain independently discovered Pages page keys and App page keys in original discovery order

Scope

This changes only which build-discovered page URLs are sent to CDN warmup. It does not change runtime route priority or handler behavior.

Validation

• 45 focused discovery/deploy-wiring tests passed
• targeted format, lint, and type checks passed
