Unspaghettit

Two new ways to see the model: where every element came from, and what it looks like as a diagram.

Added

• Source Provenance — store the file a model was extracted from and stamp every element (surface, action, rule, …) with its source span. Source Capture on the MCP side (attach_source_file → record_element_span → finalize_analysis, gated on full tracing) + a dashboard Source Viewer with bidirectional element↔span highlighting, toggle, and filter.
• Diagram Projections — project a feature or whole project into a statechart, sequence, ER, flowchart, or mindmap (plus the free behavior graph). Pure projectors emit a neutral DiagramSpec; export as Mermaid or Graphviz DOT, or download SVG/PNG.

Fixed

• Graph view fills the viewport instead of overflowing into a page scrollbar.
• Dragging the graph/diagram canvas no longer selects page text.
• Feature cards refresh their coverage score live on an MCP report.

Changed

• README slimmed to an overview; full guides moved into docs/.
• Dev server moved off WSL2-reserved 5173 to 8173.
