ajandClaude Opus 5.5 8c7dc41ce8 feat(planning): warn about tipping parts and retire legacy lead-in assignment
Plan Cutting is now the only automatic lead-in assignment, and parts the
support grid cannot hold level are reported wherever they lack a
steadying tab.

- Remove Assign Lead-ins (plate and nest), LeadInAssigner, the lead-in
  tool's Auto-Assign button and the Auto Tab size range; old settings
  with autoTab sizes still load
- Manual Place Lead-in tabs the clicked entry when support tabs are on
  and the grid cannot hold the part (SupportTabSettings)
- New PartSupport finding: Plan Cutting replay and best-effort plans
  warn when a drawing pin, a lead-in that does not fit or no single tab
  leaves a part unsteady; the pre-post review checks each placed
  program's outside tab gap. These warnings replace the advisory
  weak-tab notes; only the inside-corner tab note stays advisory, and
  never for a pin
- Pinned perimeters keep their pin but carry the support analysis
- Draw grid points as pixel-snapped squares without anti-aliasing
- Post fixtures build lead-ins through a test-only TestLeadIns helper
- Docs: support tabs, pre-post verification and planner notes
