// Best-effort wake-up signal for the host-side bash task processor.
|
|
//
|
|
// The FIFO carries no meaningful payload — it's just a poke to make the
|
|
// processor poll sooner than its 3 s idle scan. So `pokeFifo` is
|
|
// non-blocking by design:
|
|
// - O_NONBLOCK on open means we don't wedge the Node event loop when no
|
|
// reader is attached (the previous writeFileSync would hang forever
|
|
// in that case, surfacing as "NetworkError failed to fetch" in the UI
|
|
// when the request never returned).
|
|
// - All errors are swallowed; the processor will pick the task up from
|
|
// the on-disk JSON via its idle scan even if the wake-up is lost.
