Expand the OpenAPI spec from 11 to 39 endpoints covering Runs, Workflows,
Verifications, Retros, Sessions, Insights, Settings, and Projects with ~45
schemas. Add `--demo` flag to `arc serve` that serves static demo data for
all endpoints (auth disabled, read-only). Non-demo mode returns 501 for new
endpoints while existing run handlers continue working.
Regenerate the TypeScript API client and add `apiJson` helper. Wire all 19
React route files with server-side loaders that fetch from the API and map
snake_case responses to camelCase UI types. Mock data kept as fallback.

Introduce semantic CSS custom properties (page, panel, fg, line, overlay,
etc.) that swap values via .light/.dark class on <html>. An inline script
reads localStorage / prefers-color-scheme before first paint to prevent
flash-of-wrong-theme.
- ThemeProvider + useTheme hook in app/lib/theme.tsx
- Sun/Moon toggle in desktop nav and mobile menu
- .light overrides for all semantic tokens, accent colors (WCAG AA on
white), atmosphere gradient, @pierre/diffs surfaces, and chart variables
- Migrated ~30 files from hardcoded color classes to semantic tokens
- GraphViz diagrams use getGraphTheme() for light/dark hex maps
- Chart gridlines and axis labels use CSS custom properties
- Workflow card colors reference CSS vars for automatic theme switching
- Pierre diffs switch between pierre-dark and pierre-light themes
