Tanish Manku c1c33caab5 mcp: wire the OAuth provider — lazy 401, RFC 9728/8414 metadata, DCR, CIMD, validating /authorize
src/auth/oauth.ts configures @cloudflare/workers-oauth-provider: /mcp and
legacy /sse protected; /authorize (ours), /token and /register (library);
CIMD enabled (with global_fetch_strictly_public in wrangler.toml); scopes
read:account/read:jobs/read:catalog; 1h access, 30d idle refresh; error
logging by code/category only. `resource` and `authorization_servers`
are derived per request origin so one build serves every environment;
production sets workers_dev = false so its only origin is canonical.

src/index.ts checks the environment invariant first (a misconfigured
deploy fails even /token), then hands off to the provider. src/runtime.ts
holds the memoized config+app. src/auth/authorize.ts validates the OAuth
request via parseAuthRequest, renders unknown-client errors locally and
client-validated errors as redirects, and stops at 501 — it never
auto-approves. src/mcp/handler.ts is a 501 stub reachable only with a
valid token.

Tests (10): 401 + resource_metadata challenge on /mcp and /sse, bogus
bearer → 401 not 500, health still reachable; PRM at root and /mcp
paths with derived resource and this origin as issuer; AS metadata with
S256, CIMD flag, "none" auth method, iss support, registration and
revocation endpoints; /authorize 400 locally on malformed and unknown
client, 201 DCR then 501 with no redirect.

pnpm check: typecheck, eslint, prettier, 87 tests passing.
