feat(graph): pipeline graph improvements — on_failure, tooltips, bus-bar connectors, skipped colouring, HTML and Mermaid output
- when: on_failure visual distinction: red circle (#d9534f), X-mark icon, dashed chip border, and Mermaid classDef; legend entry added - Job tooltip / detail panel: each chip wrapped in <g data-job="…"><title>…</title> <desc>…</desc> so SVG viewers and the HTML sidebar show stage, when, image, needs - Multi-job connector accuracy: classic mode now uses a bus-bar pattern (vertical rail at midpoint + per-job stubs) instead of one center-to-center line per stage pair - Blocked/skipped state colouring: RenderPipeline and pipelineSVG accept *cicontext.Context; skipped jobs rendered in grey (#868686) with dimmed text - Interactive HTML output (--format html): self-contained .html with inline SVG, mouse-wheel zoom, drag-to-pan, double-click reset, and a click-to-open sidebar - Mermaid pipeline output (--format mermaid): prints existing Pipeline() flowchart to stdout; suitable for mermaid.live or Markdown embedding - imageString() helper to extract image name from string or map form - 100% statement coverage maintained; 809 tests pass Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
