fix: vergilius fnptr import, remove tab pin, flatten workspace tree, middle-click close

- Fix vergilius_to_rcx.py to detect function pointer syntax (*Name)(params) and emit FuncPtr64
- Re-fetch 85 structs to recover proper field names (697/716 fixed)
- Remove pin button from dock tabs and all pin-related context menu items
- Fix newClass() creating duplicate tabs
- Set workspace tree font to match tab bar (size 10)
- Flatten workspace tree: remove redundant Project group node (VS Code Explorer style)
- Add middle-click to close dock widget tabs
- Allow type chooser to show cross-doc types for root nodes
