* Initial plan
* Update documentation to clarify error handling per SEP-1303
- Updated McpErrorCode.InvalidParams documentation to clarify it's for protocol-level errors (malformed requests, unknown primitives)
- Updated CallToolResult documentation to distinguish between tool execution errors and protocol errors
- Updated McpProtocolException documentation to emphasize it's only for protocol-level errors
- Added test to verify input validation errors are returned as tool execution errors (IsError=true)
- Implementation already correctly handles input validation as tool execution errors per SEP-1303
