fix(repl): skip /quit on EOF when stdin is not a TTY (#724)

Browse Source 
When running as a launchd/systemd daemon, stdin is /dev/null.
rustyline reads EOF immediately and the REPL thread was sending
a /quit message, causing the agent to shut down right after
startup — making service mode non-functional on both macOS and Linux.

Fix: check std::io::stdin().is_terminal() before sending /quit on
EOF. In daemon mode (no TTY) the REPL thread exits silently, leaving
other channels (gateway, telegram, …) running as expected.

Fixes #723
