supercode-harness 0.4.20

//! The orchestrator's home, its daemon lease, and the service unit the
//! operator verbs print (ORC-7).
//!
//! supercode does not perform orchestration; the `supercode-orchestrator`
//! package does (`docs/ORCHESTRATOR-IR.md` §0.1). This module holds the three
//! facts supercode's own surfaces need about it:
//!
//! * **where its state lives** — `SUPERCODE_ORCHESTRATOR_HOME`, default
//!   `~/.supercode/orchestrator`, resolved once in
//!   [`crate::HarnessHomes::orchestrator`]; the root folder IS the `default`
//!   profile and `profiles/<name>/` are the named ones
//!   (`docs/ORCHESTRATOR-IR.md` §6).
//! * **whether the daemon is up** — the lease file `<home>/orchestrator.lock`,
//!   plus a liveness signal on the pid it names. A lock whose process is gone
//!   is stale, never "up".
//! * **what a service unit for it would say, and whether it is installed** —
//!   [`service_unit`] renders the launchd plist / systemd unit `setup` writes
//!   under `<home>/service/`; [`install_service`], [`uninstall_service`] and
//!   [`service_status`] drive `launchctl` / `systemctl --user` over it.
//!
//! The lease FILE is written by the daemon itself (`bin/orchestrator.mjs`), not
//! by this crate: one writer means a service-managed daemon reports the same
//! lease a foreground one does, and a lock left by a process that is gone is
//! the daemon's own signal to replay (§4.7).
//!
//! Reading the folder is every existing ORCH reader's job: `jobs`, `runs`,
//! `routes`, `channels`, `triggers`, `profiles` and session discovery point
//! their Hermes-shaped code paths at these same profile folders.
