fix: update rmcp type aliases to non-deprecated versions

Renamed deprecated type aliases following rmcp library update:
- CallToolRequestParam → CallToolRequestParams
- InitializeRequestParam → InitializeRequestParams
- PaginatedRequestParam → PaginatedRequestParams

Also added required `meta` field to ClientInfo and CallToolRequestParams.
