flutter_concrete 0.2.0

Concrete ML FHE client for Flutter. Native TFHE-rs encryption/decryption via Dart FFI with quantization support.

0.2.0

• Dynamic key topology: Keygen reads client.specs.json from client.zip instead of hardcoded key counts. Supports any Concrete ML circuit.
• Multi-width encrypt/decrypt: Dispatches to FheUint8–64 / FheInt8–64 based on encoding width. No longer limited to uint8/int8.
• Model change detection: SHA-256 hash of topology + encoding stored in KeyStorage; keys auto-regenerate when the model changes.
• Int64List I/O for quantization with dynamic bit-width clamping
