implement the CAEP 1.0 event vocabulary#1

Add typed payloads for all eight OpenID CAEP 1.0 event types and register their decoders with go-secevent, so a parsed Security Event Token's events decode to typed Go values and CAEP events can be built back into a SET. This is the substance of the library; the stub package becomes a real vocabulary. Each event embeds a common Base envelope carrying the optional CAEP §3.1 fields (event_timestamp as go-secevent's NumericDate, initiating_entity, reason_admin, reason_user); the subject stays the SET's sub_id and is not duplicated on the event. The eight types are SessionRevoked, TokenClaimsChange, CredentialChange, AssuranceLevelChange, DeviceComplianceChange, SessionEstablished, SessionPresented, and RiskLevelChange — the last of which the original scaffold brief's expected list omitted but CAEP 1.0 §3.9 defines. Registration follows go-secevent's documented idiom: a single init calls RegisterEventType once per event-type URI, so a side-effect import wires the whole vocabulary (the database/sql-driver pattern). A generic decoder keeps that to one function. Decoding is lenient — unknown enum values and unrecognized members are preserved, the latter as json.RawMessage that re-emits byte-stably, so an event from a future CAEP profile survives a decode/encode cycle. Strictness is opt-in via Validate, which checks the required-field MUSTs and returns errors.Is-matchable sentinels. Tests cover registration completeness, typed-field extraction, lenient enums, open-extension round-tripping, the producer/consumer path through a real SET (Put then Parse then Typed), malformed-payload errors, and the required-field MUSTs. A conformance suite round-trips a spec-shaped golden fixture for every event type (CAEP 1.0 ships no machine-readable vectors). Statement coverage is ~91%.

Brings go-caep from a stub to the full OpenID CAEP 1.0 event vocabulary.
