Module socket 

Functions

cleanup_socket

Remove socket file if it exists. Best-effort, never panics. Sockets now live in ~/.synaps-cli/run/ (mode 0700), so symlink attacks from other users are not possible. Still refuse symlinks as defense-in-depth.

listen_session_socket

Bind a Unix socket at socket_path, accept connections, parse incoming events, push to queue. Runs until shutdown is set.
