Window Drag/Resize + Validator Source Fixes (March 2026)

Today we addressed a group of related issues across drag, resizer, window, and the package-validator app:

• Fixed zoom/scaling delta mismatches for drag + resize interactions by moving pointer-delta math into the correct local coordinate space.
• Updated resizer drag flow so drag-phase transforms/snapping are committed to current rect state during drag, which keeps handles aligned with snapped geometry before release.
• Updated window-to-resizer syncing so handle positions follow full window rect changes (x, y, width, height) and use the current window rect for external repositioning.
• Added validator heartbeat coverage for:
  • scaled drag behavior
  • drag-phase snapping behavior
  • window handle updates during snap drag and external window movement
• Fixed validator source separation so published mode does not accidentally resolve nested imports back to workspace packages.

Result: published and workspace routes now show meaningful behavioral differences when package versions differ, and interaction fidelity under zoom/scale is consistent.
