Subject: [PATCH 1/2] fix(slack): add exception handling to socket listener

_handle_message() in _on_socket_request() had no try/except. If it
throws (bus full, permission error, etc.), the exception propagates up
and crashes the Socket Mode event loop, causing missed messages.

Other channels like Telegram already have explicit error handlers.

Fixes #895
