Google ADK JS 2.2.1 adds ToolCallIntegrityPlugin for agent tool-call integrity checks
What changed
Google released ADK JS 2.2.1 at 22:09:39 UTC on October 6, which is early October 7 in Beijing. The release adds ToolCallIntegrityPlugin in parity with ADK Python and reserves `__adk_internal_` customMetadata keys for ADK. It is a small release, but it formally brings tool-call integrity support into the JavaScript Agent Development Kit and strengthens separation of framework-internal tool metadata.
