Florian BRUNIAUX 222a2ed39c feat(guide): add Pencil (IDE-native canvas) to Product Designer workflow
Add comprehensive documentation for Pencil, a new IDE-native design canvas tool launched January 2026.

Changes:
- guide/ultimate-guide.md (Wireframing Tools section):
  - Added Pencil to tools comparison table (after tldraw)
  - Added detailed description with features, founder info, disclaimer
  - Note: Launched Jan 2026, strong traction (1M+ views, a16z funded) but still maturing

- guide/workflows/design-to-code.md:
  - NEW section "Alternative: Pencil (IDE-Native Canvas)" (~115 lines)
  - Architecture explanation (WebGL + AI agents + Git-native)
  - Comparison table: Pencil vs Figma MCP
  - When to use (good fit / consider carefully)
  - Setup instructions + example prompt
  - Founder & backing details (Tom Krcha, ex-Adobe XD, a16z Speedrun)
  - Maturity note with recommendations

- machine-readable/reference.yaml:
  - Added 3 entries: pencil_canvas, pencil_workflow, pencil_vs_figma

Positioning:
- Pencil complements Figma MCP (not replaces)
- Target: Engineer-designers, code-centric teams on Cursor/VSCode/Claude Code
- Format: .pen JSON (open, git-versionnable)
- AI agents: Multiplayer parallel (unique feature)
- MCP: Bi-directional read+write (vs Figma read-only)

Status: Early but promising (score 3.5/5)
- Strong founder (Adobe XD co-creator, 2 exits)
- Solid funding (a16z + KAYA VC)
- Viral traction (1M+ views, FAANG signups)
- Currently FREE, pricing TBD

Disclaimers included for maturity/pricing uncertainty.
