POST /api/library/datasheets now writes an IC inbox card or a
passive/discrete model. Empty pintables never enter library/extracted.
AF Board+AI runs after unchanged run_pcb_checks (PE-SI / HF line stay).
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.
