Valentin KleinandClaude Opus 5.5 24a3954b39 Light and System interface themes (System follows the OS appearance live) (#179)
* Light and System interface themes (System follows the OS appearance live)

CADCraft had one hard-coded dark interface: Tokens::get() always returned
Tokens::DARK and Visuals::dark() was installed once at startup.

- theme.rs: Tokens::LIGHT (light grey chrome, dark text) beside the unchanged
  Tokens::DARK; Tokens::get() returns the palette of the theme in use (a
  UI-thread thread-local set once per frame). Both egui styles are built from
  the tokens and egui is switched to the shown theme, so standard widgets,
  menus and popups follow too. The drawing area (canvas, grid, axes,
  selection, grips, ViewCube, UCS icon) keeps its model-space colours in both
  themes: drawing colours are not part of the interface theme.
- ThemePref { System, Light, Dark } in UiState (`theme`), resolved every
  frame against ctx.system_theme(), so System follows the OS (winit, or the
  browser's prefers-color-scheme) live without touching the saved choice.
  No reported appearance: System shows Dark (SYSTEM_FALLBACK). Default stays
  Dark (today's look).
- View > Interface Theme > Use System Setting / Light / Dark (ui.theme.system,
  ui.theme.light, ui.theme.dark) and ui.theme {theme} for scripts and the
  control channel; ui.inspect reports the theme shown.
- Hard-coded colours on the command line (history, border, keywords,
  AutoComplete list), the status-bar message and the layer status icon go
  through tokens; overlays drawn on the canvas use a new canvas_ink token.
- Desktop app: the choice persists via eframe storage (`persistence`
  feature, key cadcraft.prefs); window geometry and egui memory are not
  persisted, as before.

Fixes #59.
