Replace bare except clauses with except Exception throughout

Bare `except:` also catches BaseException subclasses like KeyboardInterrupt
and SystemExit, which can silently swallow signals or interfere with normal
interpreter shutdown. Replaced all occurrences across cli.py, mux.py,
probe.py, proc.py, scan.py, and tag.py.

Also replaces the two `except BaseException as e:` in mux.py for the same
reason.
