Document the published Public Preview io.temporal:google-adk:0.1.1 Java integration and its seven-scenario sample suite. Cover live/offline startup, Client/Worker registration, deterministic and Activity tools, MCP, native parallel agents, human approval, structured output, long-running callbacks, testing, and Continue-As-New.

Agent Chat is the entry point. Each message is a Workflow Update that returns its own reply, concurrent turns are serialized on the ADK session, and the main Workflow drains accepted handlers before rollover or completion. Include matching CLI commands, the Workflow interface and implementation, and replay tests. Document the 0.1.1 registration-alias behavior and ADK's Workflow-side model capability checks.

Register the guide in Java navigation and the overview, shared integration catalog, and Plugins guide. Mark streaming, native ADK observability, and agent-facing Sandboxes unsupported, with plugin follow-ups for live delivery during model Activities and replay-safe ADK tracing.

Keep this PR in draft until samples-java #811 merges. All 16 Java snippets are generated with Snipsync from tested sample commit 5e56497; their source links target main. After the samples merge, run yarn snipsync --target docs/develop/java/integrations/google-adk.mdx, recheck, and mark ready for review.

Validation:

• Node 24 production build passes, including generated Markdown and the font preload check.
• CI-scoped Vale passes for all three changed MDX pages; Snipsync marker and orphan checks pass.
• All 16 snippet bodies and source links match the tested samples.
• Java 17 on macOS and Linux: all 33 sample tests, module build, and repository-wide formatting pass.
• An isolated Temporal Service CLI check receives four Update replies across Continue-As-New and finishes with the final reply.
• git diff --check passes. Live Gemini was not exercised.
