📄 Description

docs(siwe): clarify chainId parameter requirements and add chain examples

  • Fix misleading "optional" description for chainId parameter
  • Use conditional format: "optional for Ethereum mainnet, required for other chains"
  • Add chain-specific examples (Polygon, Arbitrum, Base) showing required chainId values
  • Add warning callout explaining chainId must match SIWE message Chain ID
  • Prevent 401 verification errors from chainId mismatches that confused developers

The chainId parameter was documented as "optional" but actually required for all non-mainnet chains, causing verification failures. Now clearly explains when it's optional vs required.

Summary by cubic

Clarifies SIWE chainId docs: optional on Ethereum mainnet (defaults to 1), required on other chains, and must match the Chain ID in the SIWE message. Adds examples for Polygon (137), Arbitrum (42161), and Base (8453), plus a warning to prevent 401 verification errors from mismatches.
