feat(plugin): add wireframe generation phase and move worktrees into project

Add Phase 6.25 to elaboration that generates low-fidelity HTML wireframes
for frontend units with a product review gate. Update ticket description
template and handoff summary to reference wireframe artifacts. Add wireframe
context to the design provider.

Move all worktree paths from /tmp/ai-dlc-* to .ai-dlc/worktrees/ within
the project directory. All entry points (elaborate, construct, resume)
now ensure the worktrees directory exists and is gitignored.

 - Pull existing designs, components, and mockups relevant to the intent
 - Reference design files in unit Technical Specification sections
+- When generating wireframes (Phase 6.25), reference component names from the design system in HTML comments but maintain low-fidelity aesthetic
