Tracking ticket for RFD 128.

Implementation plan

• Validate workspace links and line ranges: Update rewriteRepositoryLinks in jp-vite/config.mjs to classify links by target and check that source links and their #L<start>-L<end> ranges exist on disk, in build and dev rendering. Also extends the docs.yml trigger so pull requests that change, rename, or delete a linked workspace file run the docs build. Mergeable independently.
• Add SourceExplorer and dev-server /__source endpoint: Adds source/index.md to jp vite sync, implements <SourceExplorer /> (file tree, Shiki highlighting, line-range highlighting and selection, Referenced by badges), and registers /__source in middleware.mjs. Depends on Phase 1.
• Emit source files in the static build: Writes source-index.json and source-files/ in withJpVite's buildEnd hook when source.publish is on, and points eligible source links at /source/?path=<path>#L... in static builds. Sets source.publish = true in JP's .jp/config.toml. Depends on Phase 2.
