Add /api/library datasheet import and component GET/PUT with no exam. Reorganize pytest into datasheet, library, schematic, PCB, and AF+AI. Document Rust criteria (none chosen; no rustup) and coding conformity.

"""Internal features (block-diagram extraction) — open-drain pull-up.
|
|
|
|
Favor: pin listed in pullup_pins with no resistor to a rail → PE-INT-001.
|
|
Against: empty internal_features is silent; listed pin with a pull-up is
|
|
silent; a pin not in pullup_pins is not guessed as open-drain.
