What to build

Add a D2Renderer adapter implementing DiagramRenderer. Produces D2 diagram language output, which has better layout control than Mermaid and renders to SVG.

D2 supports containers (for module grouping), classes with fields/methods, and styled edges — maps well to all three diagram levels.

Acceptance criteria

New adapter crate archlens-d2
Implements DiagramRenderer port
Renders project-level with containers for grouped crates
Renders module-level with dependency arrows
Renders type-level with class shapes showing fields/methods
--format d2 CLI flag works end-to-end
Tests verify D2 syntax output
