Class: MCPAuthError

Base class for all mcp-auth errors.

These errors cover configuration and authorization server discovery failures. Token verification failures are intentionally NOT represented here — MCPAuth#verifyAccessToken throws the MCP SDK's OAuthError instead, because the SDK bearer-auth helpers only map OAuthError to proper 401 challenge responses (anything else becomes a 500).
