Adds a new section explaining how proof verification works internally in the JS SDK. Covers signature verification (attestor validation via ECDSA recovery) and content validation (hash comparison against provider configuration). This helps developers understand what happens under the hood when calling verifyProof().

Agent Response

I've addressed Abdul Rashid's question about how proof verification works in the JS SDK by adding documentation that explains the verification internals.

Summary of changes:

I added a new "How verification works" section to the JS SDK proof verification documentation (content/docs/js-sdk/verifying-proofs.mdx) that explains:

1. Signature verification - How the SDK validates that proofs were signed by valid Reclaim attestors using ECDSA signature recovery
2. Content validation - How the SDK verifies that the proof's hash matches the expected provider configuration using keccak256 hashing
3. Under the hood details - The cryptographic primitives used (ethers.js verifyMessage(), canonical JSON serialization)

The technical details were derived from analyzing the JS SDK source code, specifically:

• proofUtils.ts - signature verification via assertVerifiedProof
• proofValidationUtils.ts - content validation via assertValidateProof
• witness.ts - claim data signing and hashing

I've also sent a response to Abdul Rashid in the Slack thread with a summary and link to the documentation update.
