Publish launcher status to Discord over its local IPC named pipe with
no external dependency: framed-JSON handshake and SET_ACTIVITY, a
background worker with reconnection and latest-state dedup, and silent
no-op behavior when Discord is not running.
- "Browsing the library" (game count, session elapsed) while idle;
"Playing <game>" with title id and elapsed time during emulation.
Activities always carry timestamps: Discord accepts but does not
render activities without them
- Presence flips back to browsing immediately on Stop instead of
waiting for process exit: a game wedged in a GPU driver call can
outlive termination for a while. Stop also terminates the job
object so the whole child tree dies even in that state
- Toggle in the Options panel (persisted); client id configurable in
gui-settings.json; SHARPEMU_LOG_DISCORD=1 traces queue/send/failure
