feat: add vim-style quit key bindings

Add comprehensive vim-style exit options:
- :wq and :wq! commands (write and quit)
- ZZ key combination (save and quit, like :wq)
- ZQ key combination (quit without saving, like :q!)

Uses same double-key timing mechanism as existing gg navigation.
All commands exit the application consistently with existing :quit family.
