Refactor/flake dedup and wsl input (#3)

* fix: configure docker for EDaaS WSL VDI

Enable rootful docker with the Docker Desktop proxy patch, add emmathorpe to the docker group, disable resolvconf and enable nix-ld.

* feat: flesh out work module and pin claude-code to nixpkgs unstable

Migrate git config to the settings option, fix the signing key path and email, add argo-rollouts/google-cloud-sdk and other tooling, and enable go. claude-code is sourced from the nixpkgs-unstable overlay.

* chore: update personal git, delta and editor config

Move git config to the settings option, switch to the standalone programs.delta module with git integration, add commitizen, and treat Jenkinsfiles as groovy.

* refactor: dedupe flake with mkHost and add nixos-wsl flake input

Extract a shared mkHost helper to remove duplicated home-manager scaffolding, add nixos-wsl as a flake input so the EDaaS host builds without --impure, source claude-code via a nixpkgs-unstable overlay, and expose a nixfmt formatter output.

* style: format nix files with nixfmt

* refactor: migrate to stable nixpkgs 26.05 and track upstream asahi flake

Pin nixpkgs to nixos-26.05 and home-manager to release-26.05; claude-code stays bleeding-edge via the nixpkgs-unstable overlay.

Centralize allowUnfree and experimental-features in mkHost and pin nix.registry/nixPath to the flake nixpkgs.

Replace the vendored apple-silicon-support module with the nixos-apple-silicon flake input, dropping ~8.8k lines of vendored code.

Fix stable-induced package renames: neofetch -> fastfetch, noto-fonts-emoji -> noto-fonts-color-emoji.

* refactor: adopt flake-parts with host table and scoped unfree

Wrap outputs in flake-parts.lib.mkFlake, replacing forAllSystems boilerplate with systems + perSystem. Drop the unused self argument.

Collapse the three mkHost calls into a hosts attrset mapped with lib.mapAttrs; adding a machine is now a single table entry.

Replace blanket allowUnfree with an allowUnfreePredicate allowlist (claude-code, lens). Add devShells.default (nixfmt, nil, git) and a checks.formatting nixfmt --check gate.

* docs(flake): annotate inputs, mkHost, host table and perSystem

Explanatory comments only; no eval change (drvPath identical).

* refactor(home): split home-manager into focused modules; clarify desktop scope

Break the home.nix monolith into emmathorpe/home/{default,shell,git,editor,desktop}.nix. The host table now composes desktop.nix onto graphical hosts only, so element-desktop, the Sway session vars and cursor theme are no longer installed on the headless WSL host.

Consolidate chat apps: legcord moves from user.nix (system) into the home desktop module alongside element-desktop. The tty1 'exec sway' autostart moves into desktop.nix so it never runs on headless hosts.

Desktop functionality: add xdg.portal (wlr + gtk) in swaywm.nix to enable screen sharing and native file pickers for Element and Firefox under wlroots.

* feat(desktop): declarative Sway config with idle-lock, notifications and bar

Add emmathorpe/home/sway.nix managing wayland.windowManager.sway (package = null, reusing the system Sway wrapper) plus swaylock, swayidle, dunst and an i3status-rust bar. home-manager's systemd integration wires sway-session.target so the swayidle/dunst user services start with the session.

swayidle locks after 5 min, powers outputs off after 10, and locks before sleep. Media/brightness keys use wpctl (pipewire) and brightnessctl; the launcher is sway-launcher-desktop in a floating foot window; keyboard is set to dvorak to match the console.

Move swaylock/swayidle/dunst/i3status-rust out of the system programs.sway extraPackages (now home-managed). Add security.pam.services.swaylock on the MBP host so the lock screen can authenticate (X1 already had it with fingerprint auth).
