GitHub Actions workflow screenshots.yml: workflow_dispatch + push trigger on themes/** and fixtures/**. Installs Nix, runs litmus-capture capture-all, uploads to R2, updates manifest.

Summary of Changes

Created .github/workflows/screenshots.yml with:

  • Triggers: workflow_dispatch (with optional provider/theme/fixture filters) + push on themes/, fixtures/, crates/litmus-capture/**
  • Environment: WLR_BACKENDS=headless + WLR_RENDERER=pixman + LIBGL_ALWAYS_SOFTWARE=1 for GPU-free headless Wayland
  • Steps: Nix install → cargo build litmus-capture → capture-all → manifest build → coverage check → aws s3 upload to R2
  • Uses R2_ACCESS_KEY_ID, R2_SECRET_ACCESS_KEY, R2_ENDPOINT GitHub secrets
  • Reports screenshot count and staging size in job summary

Note: Headless Wayland capture requires testing on actual runner; may need to add Mesa software rendering packages or adjust WLR/GL env vars.
