chore: update dependencies + migrate to @iden3/react-native-rapidsnark 0.0.1-beta.2 (npm)

[Copilot]

Migrates from a local path reference to the published @iden3/react-native-rapidsnark@0.0.1-beta.2 npm package and updates all iden3/polygonid dependencies to their latest compatible versions.

API Migration

The new rapidsnark package changed its native interface: groth16_prover (byte array in-memory) → groth16Prove (zkey file path + base64 witness), and groth16_verify argument order changed.

share/proof/prove.ts — writes proving key to a UUID-named temp file, calls new API, cleans up in finally:

const zkeyPath = `${tmpDir}/proving_key_${uuidv4()}.zkey`;
await RNFS.writeFile(zkeyPath, fromByteArray(provingKey), 'base64');
const { proof, pub_signals } = await groth16Prove(zkeyPath, calcResult);

share/proof/verify.ts — swapped argument order to match new signature (proof, inputs, vk):

return await groth16Verify(
  JSON.stringify(proof),
  JSON.stringify(pub_signals),
  byteDecoder.decode(verificationKey),
);

Breaking API changes from updated packages

• @iden3/js-jwz@1.13.1 — ProvingMethod interface now requires get supportedCircuits(): string[]; added to ProvingMethodGroth16AuthV2
• @0xpolygonid/js-sdk@1.43.0 — AbstractPrivateKeyStore now requires list(): Promise<{alias, key}[]>; added to AppStoragePrivateKeyStore

iOS note

Podfile.lock needs regeneration via pod install after merge — the new react-native-rapidsnark podspec adds a dependency on the rapidsnark CocoaPod (0.0.1-beta.2).
