**Sections, the modelling-tools batch, AI modelling, and the performance marathon.**

Highlights:
- **Section planes, complete**: hover plane inference, one active cut per context, thick cut edges + section fill, symbol balloons and toolbar; scenes and `.igz` remember the cut; the composer clips its hidden-line pass too — real plans and sections on sheets.
- **Tool parity batch**: Flip (Ctrl = copy), Make Component (G), Freehand, Pie arc, chord bulge/radius in the Measurements box.
- **AI Assistant + AI Bridge (MCP)**: model with an AI from inside the app (every edit = one undoable command) or with Claude from outside over MCP.
- **Native glTF/GLB import**, starter CC0/CC-BY components, texture library, translucent glass.
- **The performance marathon** from a real 280k-face project: the paste "not responding" hang is dead (`Scene.bounds` cached), Move/Rotate/Paste preview through frozen scratch VBOs, pasting a 230k-face group went from ~12 s per stamp to instant (copies share the definition), erase/box-select/silhouette freezes vectorized away.
