Reliable letter-based default keybinds + kitty keyboard protocol

alt+tab is grabbed by desktop WMs and alt+arrows are re-encoded or
swallowed by several terminals, leaking plain arrow keys into the
focused window. Primary defaults are now letter chords which every
terminal delivers via ESC-prefix: alt+w (switcher), alt+h/alt+l
(snap), alt+m (maximize). The alt+tab/arrow variants stay as extra
bindings, and standalone/client now enable the kitty keyboard
protocol (DISAMBIGUATE_ESCAPE_CODES) when the terminal supports it
so even those are delivered unambiguously (Konsole 23.08+, kitty,
foot, wezterm, ghostty). 34/34 integration checks.
