Adds a single tmux Alt+p fzf palette that opens nvim/lazygit/shell as styled
tool windows for the current session's project, or clones a fresh harness with
the same project+model. Bridges via run-shell (expands #{window_name}) into a
new 'hqt palette' CLI subcommand, since display-popup does not format-expand its
command (verified on tmux 3.6b).
