Remove the wofi subprocess entirely. The launcher now renders its own
Wayland overlay window via gtk4 + gtk4-layer-shell: a SearchEntry at
the top with live fuzzy filtering, a ListBox of results below, and
keyboard navigation (Enter/Esc/arrows). Toggle (keybind press while
open closes it) is handled via a PID file in $XDG_RUNTIME_DIR.

Zero-dependency Rust rewrite of the breadboard launcher. Parses
.desktop files in-process (no awk subprocesses), builds a tab-separated
cache for wofi dmenu, and supports stale-while-revalidate background
rebuilds. Apps-only for now; icon support to be added later.
