Auth Worker served on the auth subdomain. A Hono app handling authentication. Binding-dependent behavior (database queries) is stubbed for now — no real KV/D1/DO bindings yet.

Routes

Method	Path	Description
GET	`/eac/challenge`	EAC challenge, served as text
GET	`/cachedlogin/forplatformid/:platform/:id`	Cached logins (stubbed → `[]`)
POST	`/connect/token`	OAuth token endpoint, issues a JWT
GET	`/role/developer/:id`	Developer role lookup (TODO)

Notes / TODO

JWT is signed with a placeholder dev secret in src/jwt.ts. Move to a secret binding before real use.
/eac/challenge content is inlined in src/auth.app.ts (Workers have no filesystem) — replace EAC_CHALLENGE with the real challenge text.
/cachedlogin/... and the RoomInstance cleanup in /connect/token need a DB binding to be implemented.
/role/developer/:id is a stub (// TODO: implement).
