fix(ci): momoto stub crates for cargo metadata + website build step

- Replace git clone (fails for private repo) with cargo-metadata stubs
- Stubs provide Cargo.toml + empty lib.rs for momoto-core/metrics/intelligence
- color-science feature disabled (--no-default-features --features headless)
  so stubs are never compiled, only resolved by cargo metadata
- Support MOMOTO_TOKEN secret for authenticated clone if available
- Add npm ci && npm run build before Cloudflare Pages deploy
