Franken OCR

A pure-Rust, memory-safe, CPU-only OCR engine for a small family of hand-ported vision-language models. Baidu Unlimited-OCR is the fast default for document OCR, GOT-OCR2 handles specialized structured formats, SmolVLM2 handles image description and VQA, OneChart extracts chart data, and Polyphonic-TrOMR turns full scanned sheet-music pages or staff crops into MusicXML through --task music. All five runtime models are available through focr pull; TrOMR publishes both the 61 MB int8 default artifact and an 86 MB f32 reference artifact. The v0.7.0 Unlimited-OCR artifact uses the conservative exact recipe and passes the hard-page termination and complete 20-page corpus budget. The models run through model-specific Rust kernels and need no general ML framework, Python, CUDA, FFI at inference, or GPU.
