fix(sling): remove obsolete --naked flag

The --naked flag (skip tmux session creation) was a vestige of an earlier
design requiring manual session management. With the current polecat
architecture where polecats are witness-managed, ephemeral, and self-deleting
after task completion, manual session management is no longer needed.

The flag also created invalid states (e.g., slinging to crew --naked left
them unreachable since crew require tmux sessions for communication).

Closes gt-xhn5s
