What replaced CGEventPost in my Stream Deck daemon

I press the Stream Deck key. The daemon logs the press, synthesizes `Cmd+Opt+;` through CoreGraphics, and exits cleanly. Wispr Flow does nothing. Three Apple subsystems and one decompiled Electron bundle later, the working trigger turned out to be a one-line URL.

The plan was the boring kind: Stream Deck key (the physical button on Elgato’s programmable USB grid) → WebSocket message → my daemon (long-running background process) → synthesized global hotkey → Wispr Flow’s hands-free dictation starts (Wispr Flow is the voice-to-text Mac app that types your speech into the focused window) → I talk → words show up in my editor. I’d done variants of this with osascript (macOS’s command-line AppleScript runner) years ago. Should have taken an afternoon.
