/**
 * Kitty multiplexer implementation
 *
 * Uses kitty's remote-control CLI (`kitten @`) to manage windows.
 * A kitty WINDOW is the 1:1 equivalent of a tmux pane (full PTY).
 *
 * Requires `allow_remote_control` **and** `listen_on` in kitty.conf. When
 * `listen_on` is set, kitty exports `KITTY_LISTEN_ON` to its child processes
 * (including OpenCode). The plugin passes that env through to `kitten @` so
 * remote control goes via the socket instead of the controlling terminal,
 * because OpenCode spawns subagent commands in a process detached from the
 * kitty window's tty, where the tty-based remote-control path does not work.
 *
 * Layout mapping:
 * - main-vertical → tall layout (full-height main pane on left, side panes stacked on right)
 * - main-horizontal → fat layout (full-width main pane on top, side panes tiled below)
 * - tiled → grid layout (equal-sized cells)
 * - even-horizontal → horizontal layout (all panes side-by-side)
 * - even-vertical → vertical layout (all panes stacked)
 *
 * Maps each plugin layout to the closest kitty built-in layout. kitty has no
 * per-window layout API, so the chosen layout is applied as a global change to
 * the active tab (overriding whatever layout was active there).
