// Minimal electron stub for bundling src/main/*.ts under plain Node
// (tests/ssh-session-e2e.mjs, tests/commands-store.mjs). Only what the bundled
// modules touch.
//
// Every mutable piece of state lives on `globalThis.__otElectronStub` rather
// than in this module's scope: the bundles INLINE this file (esbuild aliases
// `electron` to it), so a test requiring both `./electron-stub.cjs` and a
// bundle would otherwise get two independent copies, and registrations made by
// the bundled code would be invisible to the test.
//
// `app.getPath('userData')` defaults to `OT_STUB_USERDATA` and is also settable
// via `__setUserData`, so a test can point the settings store at a temp dir and
// exercise settings-driven behavior.
