Fix security vulnerabilities and request handling bugs

- Move page cache out of the publicly served .bunext/public dir and hash cache keys
- Skip caching credentialed requests, non-2xx and Set-Cookie responses; cap entries
- Enforce API body size limit while reading; keep req body readable for handlers
- Hide error messages from clients in production
- Escape inline script JSON; strip cookies from HMR payloads
- Only trust X-Forwarded-Proto with trust_proxy config
- Fix console race in SSR, dotted page paths, middleware rewrites,
  excluded path status, encoded static file names, symlinked dirs
- Upgrade vulnerable deps, remove micromatch, pin bun versions, delete dead code
