## 0.1.0

* Signing in with OpenID Connect's code flow, with a SimpleLogin preset: attempts,
  the ID token's checks, identities, the stock endpoint and the parts, the forwarding
  page.
feat(oidc): a Serverpod module for signing in with OpenID Connect, SimpleLogin a preset (ADR 0023) halkyon_oidc_server and its generated client halkyon_oidc_client: any provider following OpenID Connect's code flow, beside Serverpod's own providers, with a preset for SimpleLogin (no PKCE, no `typ`). Nothing of Halkyon's is in it; BSD-3-Clause, `publish_to: none` for now. - Attempts in `halkyon_oidc_attempt` (ADR 0020's D13): the ID PostgreSQL's gen_random_uuid(), a state and a nonce of 32 random bytes, PKCE's verifier where used, the caller if signed in; ten minutes, taken once. A host may begin the state with a marker. - The code exchanged by the module itself, so a provider out of reach (a timeout, a 5xx) is told apart from a refused code; the ID token checked with dart_jsonwebtoken's algorithms (ADR 0020's D12): the provider's algorithms alone, the key its `kid` names, of the right type; issuer, audience and `azp`, expiry, time issued, `nbf`, a minute's leeway; the attempt's nonce; a `sub`. - Keys kept an hour, fetched again for an unknown `kid` at most once a minute; discovery checked against the issuer; every request with a timeout. - Identities in `halkyon_oidc_identity`: the provider's key and the `sub`, one per person and provider, deleted with the person. - The stock endpoint (`OidcIdpBaseEndpoint`), and the parts for a host with rules of its own: begin, verify, keep and takeKept, link, accountOf, unlink; merging people; a limit per network. - The forwarding page, moved here from halkyon_base in the next commit. The package's main library is the code generator's, as halkyon_base's; a host imports `package:halkyon_oidc_server/oidc.dart`. ADR 0023's point 5 no longer names OAuth2PkceUtil, which the module doesn't use.
