Introduces watcher.py — a kitty Python watcher that captures terminal
scrollback to ~/.terminal_history/ whenever any window or pane is closed
via Ctrl+D, keybind, or full kitty quit. Works alongside the fish
smart_exit function, which handles graceful shell exits and sets a
user var flag to prevent duplicate logs.
Fixes the kitty.conf watcher directive (removed invalid --type=global
prefix that caused a FileNotFoundError on every kitty startup).
