paws.lua

-- Paws 🐾 — native Kaku / WezTerm integration.
-- Add this to ~/.config/kaku/kaku.lua (Kaku) or ~/.config/wezterm/wezterm.lua (WezTerm),
-- before `return config`. No code changes needed — all APIs are standard WezTerm.
-- Everything runs in-process: no external scripts, no temp files, no `kaku cli`.
--
-- The game lives in its OWN TAB (full-window, never disturbs your panes).
--   CMD+G        : open the game tab (shows a centered menu) ↔ toggle back to agent
--   CMD+SHIFT+P  : close the game tab and re-open the menu
-- The picker, Random rotation and Settings all live inside the `paws` wrapper now,
-- so the menu is centered and styled. Manual switching only — no auto-jumping.
--
-- NOTE: CMD+SHIFT+G is intentionally NOT used — Kaku already binds it (lazygit).
-- Kaku does not auto-reload config; press CMD+Shift+R after editing.
