/**
|
|
* Why: Orca writes two canonical discovery files into `<userData>/`:
|
|
* `orca-runtime.json` (RPC endpoint + authToken for the bundled CLI) and
|
|
* `agent-hooks/endpoint.env` (hook port + token for cursor-agent/claude/codex
|
|
* scripts). Without a single-instance lock, every AppImage/.app double-click
|
|
* boots a fresh Electron main that clobbers both files. When the most recent
|
|
* instance quits, metadata points at a dead pid and `orca status` reports
|
|
* `stale_bootstrap` even though the original process is still running.
|
|
*
|
|
* This helper centralises the lock gate so it is testable in isolation and
|
|
* so `src/main/index.ts` has one clean call site rather than two spread-out
|
|
* Electron calls.
|
|
*
|
|
* Electron derives the lock identity from the current `userData` path, so
|
|
* callers MUST invoke this AFTER `configureDevUserDataPath(is.dev)` — that
|
|
* way dev (`orca-dev` userData) and packaged (`orca` userData) runs lock in
|
|
* separate namespaces instead of serialising against each other.
