jpmschweitzerandClaude Opus 4.6 1d4b9cf299 chore(skills): add d2-diagram skill for text-to-diagram generation
Wraps d2 CLI (v0.7.1) with project defaults: theme 200 (Dark Mauve),
dagre layout, PNG output. Includes render/validate/batch scripts,
syntax guide, and five category templates (architecture, entity,
data-flow, state, UI flow).

Usage: $(basename "$0") [directory] [options]
Batch render all .d2 files in a directory. Skips files whose PNG is
newer than the source unless --force is used.
Options:
--dry-run List files that would be rendered
--force Re-render even if SVG is up to date
--theme N Override theme for all files
Examples:
$(basename "$0") # All in docs/diagrams/
$(basename "$0") docs/diagrams/architecture/ # One category
$(basename "$0") --dry-run # Preview
$(basename "$0") --force # Re-render everything
