- src/bot.py: log in as the bot user with the stored token, prime past history,
and on a new message in a mapped room run `ssh -> gui-launch.sh` (built with
shlex.quote). The all-projects room fans out to every repo, each session named
"<repo> - <date>". Launch failures are reported back into the room.
- scripts/gui-launch.sh: propagate MB_SESSION_NAME into the launched session.
- requirements.txt: matrix-nio.
Connectivity (sub-step 1) verified on the Mac; launch (sub-step 2/3) to be tested
on the Spark, where the SSH alias resolves.
