Auto-detection is useless in the deployment this ships in, measured on tor-ms22.
Terminal identity lives in env vars set by the emulator (KITTY_WINDOW_ID,
TERM_PROGRAM) and docker exec does not forward them — pi inside the container
sees only TERM=xterm-256color no matter what is rendering it. So the =desktop
detection can never see Kitty from in there and always falls through to OSC 777,
which Kitty does not implement. Result: on a containerised client the ping
silently does nothing, which is the worst available failure for a feature whose
entire purpose is to break a silence.
Adds MEMPALACE_MAILBOX_NOTIFY=kitty and =osc777 to force one protocol and skip
detection. =desktop keeps the notify.ts-style autodetect for the non-container
case, unset still means in-TUI only, 0/off still silent. The Windows toast branch
is dropped from the comment rather than the code path it never had here: it needs
powershell.exe on PATH, which is a WSL fact, not a Linux-container one.
