Make internal/theming.List the single source of truth for themes:
- Drop tui.BuiltinThemes, tui.ThemeByID, and the NvChadTheme field on
tui.Theme. tui.Theme is now a thin {ID, Name} display value.
- Wizard populates its dropdown from theming.List() and uses
DisplayName for the label.
- neovim.resolvedTheme uses theming.Get (with theming.List()[0] as a
fallback) instead of a caller-supplied []tui.Theme slice.
- neovim.New signature loses the themes []tui.Theme parameter; update
cmd/archduino/main.go and all neovim tests to match.
Break the resulting neovim→theming import cycle (theming previously
imported neovim for WriteChadrc) by inverting the dependency:
theming exposes a ChadrcWriter function hook, and neovim registers
its WriteChadrc into it via package init. The theming test stubs
ChadrcWriter directly to exercise the chadrc-rewrite branch without
pulling neovim in and re-creating the cycle.
Delete the now-obsolete TestBuiltinThemesCarryNvChadName / TestThemeByID*
tests in internal/tui/state_test.go — their coverage lives in the
theming package's own tests.
Adds a themeID parameter to buildRegistry (unused in the body until
Task 7 wires neovim.New) and rebuilds the registry after the wizard
returns with finalState.ThemeID, so the dashboard runs against a
registry configured with the user's theme selection. The pre-wizard
call passes "" since only the dashboard path consumes theme-aware
modules.
- neofetch was removed from Arch's official repos; fastfetch is the maintained replacement.
- ExecRunner.Run previously discarded stderr, so any 'sudo pacman' failure surfaced only as 'exit status 1'. Now the returned error includes the captured stderr (matching what Output already did).
Replace the init()-time hello toy-module registration with a
buildRegistry(cfg) helper called from the install RunE that wires the
ten Plan 3a modules (packages, gittools, starship, yazi, zsh, fonts,
zellij, themes, arduinocli, shellconfig) against a shared ExecRunner,
Pacman, Yay, and GitClient.
