Add a GitHub Actions workflow that detects Ruby version+platform combinations missing from the R2 mirror and builds them from source. This addresses gaps where upstream ruby-builder hasn't published builds for certain versions on Linux/macOS. - Create gap detection script (scripts/detect-ruby-gaps/) that queries upstream sources and compares against R2 metadata - Create build-ruby-from-source.yml workflow with detect-gaps, build, and trigger-manifests jobs across all 6 platforms - Fix manifest generator to handle "built-from-source" source_url by probing R2 for actual binary extensions - Add "source" field to manifest schema and ManifestDownload struct to flag built-from-source entries - Add auto-replace logic to mirror-binaries so upstream binaries overwrite built-from-source entries during sync
