feat(framework): auth in core — Bearer/Basic mechanism + principal slot
- http/auth.wo: auth_header (scheme split, case-insensitive, RFC 9110),
bearer_token, basic_credentials (first-colon split, RFC 7617),
pure-.wo base64_decode (RFC 4648, strict padding), ct_eq constant-time
compare (no early exit, both Basic fields always compared)
- req.principal: the blessed "who is this" slot, "" until authenticated;
Middleware.before now takes mut req so auth can write it
- BearerAuth { token, principal } and BasicAuth { user, pass, realm }
middlewares; BasicAuth answers the WWW-Authenticate challenge; policy
(routes/users/secrets) stays app-side on the exposed fns
- web-app dogfoods BearerAuth; its hand-rolled Auth class deleted
- probe matrix 26/26 (RFC 4648 vectors, rfc7617 pair, pass-with-colon,
bad padding/chars/length, deny paths, challenge header) release+ASan
- gate grows 16 -> 17: wrong bearer token answers 401 over the wire
- README: auth bullet + the core CHECKLIST (done / candidate / parked
behind 8-11 by design); story 16 + board record the landing
- all gates green: web-app 17/0, oop-e2e 89/0, deps-accept 8/0,
log-watcher 7/0, employee 8/0, woc-test green
