Merge pull request #50 from nostrability/feat/mip-00

Introduces MIP-00 support by adding Kind 443 (KeyPackage) and Kind 10051
  (KeyPackage relay list) event schemas, plus auxiliary MLS tag schemas
  (protocol version, ciphersuite, extensions, client) with matching aliases.
  Tightens content validation for Kind 443 to require even-length hex.
