fix(desktop): claim TERM_PROGRAM=kitty in v1 terminal

[Kitenite]

Mirrors the host-service v2 path so chat TUIs (claude-code et al.) parse kitty CSI-u sequences from xterm.js. v1 already enables kittyKeyboard in the renderer; the env claim makes consumers honor it.

🐰 A whisker-twitch brings joy today,
Superset fades, Kitty's here to stay!
TERM_PROGRAM purrs with a feline name,
Shells and terminals celebrate the same! 🐱
