+ * Desktop notification utilities for task completion alerts.

+ * On Windows, fires a native toast notification via PowerShell so users who
+ * have muted speakers or stepped away still see a visual alert when the
+ * agent finishes its work (#1111). On other platforms the function is a
+ * no-op — the terminal bell (BEL character in the OSC title sequence) already
+ * provides the audible cue.
+ *
+ * The Desktop (Electron) app can call `notifyTaskComplete` directly; the
+ * CLI terminal-app path is best served by the BEL character already embedded
+ * in `setTerminalTitle`, so this module is not wired into the CLI streaming
+ * flow by default. The Desktop renderer imports and calls it after its own
+ * task-completion event.
