ignition-core 1.1.0

//! Trial-license capability models (04-03, RIG-02/03) — field names
//! match the **live-captured 8.3.x bodies** (04-RESEARCH §Code Examples,
//! re-verified live on BOTH minor versions during this plan's spike:
//! expired shape on ign-research 8.3.6, active shape on the
//! ignition-devops rig 8.3.3).
//!
//! `GET /data/api/v1/trial` answers **unauthenticated** (live-verified
//! on both rigs, both trial states) — a fresh rig has no token yet, so
//! the trait methods apply auth ONLY when the client carries a
//! credential (the plan's "cred present → headers ride along
//! harmlessly" rule; a header-less client degrades cleanly, the
//! version-command precedent).
//!
//! `POST /data/api/v1/trial` is the RESET: session-cookie + CSRF (tier
//! 1, the browser-verified mechanism — live-proven end-to-end on
//! 8.3.3: `expired:true → false`, `trialSecondsLeft 0 → 7199`). The
//! 2xx response body IS the fresh [`TrialWire`] (live-observed), so
//! the reset parse reuses this model. **State gate (live-discovered):
//! the gateway answers 403 to reset attempts on a NON-expired trial**
//! — the action layer pre-checks expiry to keep that refusal honest.
