caixa-operator 0.1.3

//! `caixa-operator` — Kubernetes controller for Caixa / Lacre / CaixaBuild.
//!
//! Responsibilities:
//!   - Watch `Caixa` CRs; for each, resolve its Git source + transitive
//!     deps via `caixa-resolver`, write a companion `Lacre` CR with the
//!     BLAKE3 closure root.
//!   - Watch `CaixaBuild` CRs; spawn a short-lived Job that runs `feira
//!     build`, collect the artifact digests, report success/failure in
//!     status + events.
//!   - Emit standard K8s conditions (Ready/Resolving/Failed) so downstream
//!     tooling (FluxCD, Argo, custom dashboards) picks them up cleanly.
//!
//! Transport:
//!   - Binary reads `KUBECONFIG` / in-cluster config via `kube::Client`.
//!   - stdout is a tracing subscriber (JSON in prod via `--log=json`).
