- treefmt-nix drives `nix fmt` and the formatting check (nixfmt/shfmt/
prettier; generated files and flake.lock excluded). Replaces the
bespoke find-based check.
- deadnix and statix as flake checks and pre-commit hooks; deadnix
ignores module-arg patterns, statix.toml disables the two house-style
lints (repeated_keys, empty_pattern). Fixed the one real deadnix hit
(unused overlay arg) and statix hit (use inherit for claude-code).
- git-hooks.nix installs the pre-commit gate via the devShell.
- .editorconfig for the base style.
- Move system/modules/work/default.nix -> lyrathorpe/home/work.nix (it is
a home-manager module). README gains a Development section; docs
reformatted by the new formatter.
