feat: implement the full Kitty keyboard protocol Adds the real push/pop/set/query progressive-enhancement flag-stack mechanism to vt/parser.odin (previously only a fixed "disabled" reply to the capability query) and all 5 flags' key encoding in new kitty.odin: disambiguate escape codes, report event types, report alternate keys, report all keys as escape codes, report associated text. Fixes two pre-existing bugs found along the way: CSI <u / CSI =...u were mis-parsed as SCORC (restore-cursor) since feed_csi never recognized '<'/ '=' as CSI prefixes, and CSI >flags u (push) was silently swallowed as a no-op. New xkb FFI (xkb_keymap_key_get_syms_by_level, xkb_state_key_get_layout, xkb_keysym_to_utf32) backs the alternate-key-reporting flag's shifted/ base-layout codepoint lookups. Release/repeat event reporting wired into events.odin's keyboard_key_cb and main.odin's fire_due_repeats. Kitty and modifyOtherKeys coexist by fallthrough in handle_key_press rather than being mutually exclusive.
