Traces are sometimes not formed correctly in the 3d viewer

These issues are inside of the 3d viewer https://github.com/tscircuit/3d-viewer

• Fix for traces "appearing jagged"
• Fix for traces sometimes overlapping holes

This might have already been done via: Update ijump algo, use multilayer autorouter.

[homie-gg]

This might have already been done via: Overlapping Port Fix (don't throw errors if pcb traces overlap if connected more distantly using connectivity map).

[homie-gg]

This might have already been done via: enable goalbox optimization.

[homie-gg]

This might have already been done via: Reorganize to better separate stories, pcb and schematic functions, add basic schematic snapshot test.

[homie-gg]

This might have already been done via: fix routing through holes (holes not recognized as obstacles).

[homie-gg]

This might have already been done via: Update 3d viewer, core and pcb viewer. Add switches to keyboard example.
