yah-cloud 0.8.43

//! [`LocalDockerEnvoy`] — tier-S, Synthetic-flavor adapter that exposes the
//! existing [`LocalDockerProvider`] through the envoy verb framework (R409-T7).
//!
//! Per W144 D3:
//! - **Tier S** — first-class; full internal-verb coverage, same contract-test
//!   scope as Hetzner.
//! - **Flavor Synthetic** — local emulation backed by containerd + MinIO; no
//!   upstream vendor to drift from, so drift detection is a no-op.
//!
//! ## Verb coverage
//!
//! | Verb | LocalDockerProvider method |
//! |---|---|
//! | `cloud.vps.create` | `ensure_project` + `create_server` |
//! | `cloud.vps.destroy` | `destroy_server` |
//! | `cloud.vps.status` | `server_status` |
//! | `cloud.object.bucket.create` | `create_bucket` |
//! | `cloud.object.bucket.delete` | `delete_bucket` |
//! | `cloud.object.bucket.exists` | `bucket_exists` |
//!
//! `location` is accepted in the wire inputs but ignored — LocalDocker runs
//! all workloads on the local machine regardless of region tag. `ssh_keys`
//! on `cloud.vps.create` are similarly ignored (no SSH injection in
//! containerd containers).
