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.
Anthropic/Gemini names resolve to DeepSeek. Extraction import path re-exports datasheet_extract. Inherited copies stay on disk. storage_gcs unused, skipped.
