feat(router): add whitelist mechanism for http driver and auth plugin

- implement route whitelist registration and wildcard matching in RouterExtension
- add cookie store session fallback when Redis is disabled in driver_http
- actively register public auth endpoints to whitelist in auth plugin
- update user handlers to persist session and clear cookie on logout
- document router whitelist mechanism in AGENTS.md and new-api skill
