Re-landed on current main (the earlier branch never merged — main moved under
it). Operators hit "permission denied" connecting to the colibri daemon from
colibri-tui / the `clawdie` helper: socket.rs binds the Unix socket but never
sets its mode, so it stays at the umask default (0755 = owner-only write).
Connecting needs WRITE perm, so a colibri-group member (clawdie) gets EACCES.
chmod the socket to 0770 after bind. Shared socket::serve, so it covers both
colibri-daemon and the clawdie agent.
