Adds a "system" theme option that queries the terminal's configured ANSI color palette via OSC 4/10/11 and maps those colors to critique's theme roles (error→red, success→green, primary→cyan, etc.). Background is set to transparent so the terminal's native background shows through. Falls back to github theme if OSC queries are unsupported.

Adding system to the global themeNames list makes it selectable in render paths that never populate cachedSystemTheme (for example, the review TUI path in runReviewMode/ReviewApp does not call renderer.getPalette + setSystemTheme). In those contexts, selecting system always resolves to the fallback github theme via getResolvedTheme("system"), so users get a misleading non-system theme. Either initialize the palette in those flows or avoid exposing system there.
Useful? React with 👍 / 👎.

Summary
systemtheme that detects the terminal's configured color palette via OSC queries and maps those colors to critique's theme rolesgithubtheme if the terminal doesn't support OSC queriesHow it works
system,renderer.getPalette()is called before the first render so the initial frame already uses terminal colorssystemat runtime (via the theme picker), palette detection runs again and triggers a re-renderChanges
