fix: scope tmux keybindings to Gas Town sessions only (#13)

Browse Source 
Use conditional bindings (if-shell) to check if session name starts
with "gt-" before running Gas Town commands. For non-GT sessions:
- C-b n/p fall back to default next-window/previous-window
- C-b a shows a help message

This prevents Gas Town from hijacking keybindings in unrelated tmux
sessions that happen to share the same tmux server.
