refactor(meta): flatten groups; only break out optional/hw-specific

2026-05-13T12:43:32Z

Drop the per-domain group fragmentation in meta/ and the parallel group-per-file structure in systemd-units/. meta/ (18 -> 6 groups): keep base, flatpak (magic), intel, nvidia, work, btc fold browser, bt, cpp, dev, extra, fonts, mail, media, nix, sound, wayland -> base (with `# --- section ---` comments preserving at-a-glance structure) drop fortran (niche; install ad-hoc when needed) systemd-units/: flatten to a single system.txt + user.txt; .ignore files move up one level; group concept and pairing rule removed. justfile: unit-list/unit-apply/unit-status no longer take a group argument. unit-add/unit-forget infer scope by probing `systemctl [--user] cat ` (system wins on tie). Top-level add/forget dispatcher updated: any unit-suffixed arg routes to unit-* without requiring a leading GROUP. docs: .github/copilot-instructions.md and README.md updated to describe the new flat layout. Pairing rule and group-token grammar gone. Pure layout refactor - no package contents change.

feat(waybar+sway): bluetooth module + unify wifi/bt toggle paths

- systemd-units/system/bt.txt: new file pairing the meta/bt.txt group; enables bluetooth.service via 'just unit-apply' - waybar: add the built-in bluetooth module; on-click runs the same bt-toggle.sh that XF86Bluetooth has always invoked. Status colors: blue when adapter is up, green when a device is connected, gray off - sway: XF86WLAN now runs wifi-toggle.sh (iwd D-Bus) instead of 'rfkill toggle wifi'. The latter required rfkill group membership (user is in wheel only), and aligning on the busctl path means the keybind and the waybar click drive the same code XF86RFKill (panic-disable all radios) keeps using 'rfkill toggle all' — that scope is genuinely rfkill-shaped.
