Introduce a new flake for the Garand-Desktop host, including:
- top‑level flake.nix with inputs and outputs
- host config (default.nix) and modules:
- hardware
- home
- system
- packages
- variables
- core boot module defining kernel and Limine loader styling
with appimage support and plymouth enabled
- Add `noctalia` input to flake and lock it in `flake.lock`.
- Include `noctalia` and `quickshell` modules in `flake.nix`.
- Extend core packages to accept `inputs` and `system`; add
`quickshell.nix`
with required Qt6 packages and environment variables.
- Enable `upower` service for battery handling.
- Add home modules `noctalia.nix` and `overview.nix` (QML UI, README,
assets, widgets, services) to provide a workspace overview.
- Comment out unused rofi and web‑search binds; update `exec‑once` to
start
the overview daemon and `noctalia-shell`.
- Provide `restart.noctalia` script and its Nix wrapper.
- Enable `noctalia-shell` in `stylix` configuration.
Enable Peaclock in the user’s home configuration and add a new
`wrappers` input to the flake. System‑level Peaclock references are
commented out, and default and digital config files for Peaclock are
included.
