ORT-Incompatible Targets (WASM, Android x86_64 emulator)

Only ORT-dependent paths are incompatible. The same paths block both WASM (no native ORT linkage at all) and the x86_64-linux-android emulator triple (no pyke prebuilt; aarch64-linux-android does ship a prebuilt and gets full ORT):

• paddle-ocr — ONNX Runtime + native C++ deps: not WASM-safe; no Android x86_64 prebuilt
• layout-detection — depends on ONNX Runtime layout models: not WASM-safe; no Android x86_64 prebuilt (RT-DETR + table classifier are available off-ORT via the layout-tract sibling, below)
• embeddings — depends on ONNX Runtime sentence-transformer models: not WASM-safe; no Android x86_64 prebuilt
• auto-rotate — depends on ONNX Runtime orientation classifier: not WASM-safe; no Android x86_64 prebuilt (available off-ORT via the auto-rotate-tract sibling, below)

Pure-Rust type-only companion features expose the public config/result types for the above without pulling in ORT:

• layout-types — LayoutDetectionConfig, TableModel, BBox, DetectionResult, LayoutClass, LayoutDetection, RecognizedTable. layout-detection implies layout-types.
• auto-rotate-types — OrientationResult. auto-rotate implies auto-rotate-types.
• embedding-presets — EmbeddingPreset (already existed; pure-Rust preset metadata).
