Disable Chrome MCP telemetry watchdog by default (#85886)

Summary:
- The PR adds the Chrome DevTools MCP `--no-usage-statistics` default launch arg, honors explicit profile usage-statistics `mcpArgs`, adds regression tests, and adds a changelog entry.
- Reproducibility: yes. source-reproducible: current main builds Chrome MCP launch args without the upstream o ... etry is initialized. I did not run a fresh failing current-main process leak loop in this read-only review.

Automerge notes:
- PR branch already contained follow-up commit before automerge: Disable Chrome MCP telemetry watchdog by default

Validation:
- ClawSweeper review passed for head 68249b1f58.
- Required merge gates passed before the squash merge.

CHANGELOG.md

@@ -67,6 +67,7 @@ Docs: https://docs.openclaw.ai
 - WebChat: keep the run-complete indicator in progress until deferred history replay renders the assistant reply, so Done no longer appears before response text. (#85374) Thanks @neeravmakwana.
 - Agents/compaction: skip agent-harness preflight for provider-owned CLI runtime sessions so over-threshold Claude CLI sessions continue through normal compaction instead of failing on a missing harness. Fixes #84857. (#84878) Thanks @zhangguiping-xydt.
 - Control UI/config: save form-mode edits from the source config snapshot so runtime-only provider defaults like empty `models.providers.<id>.baseUrl` are not written back and rejected. Fixes #85831. Thanks @garyd9.
+- Browser/existing-session: launch Chrome DevTools MCP with usage statistics disabled by default so its telemetry watchdog stays off unless an operator explicitly opts in. (#85886) Thanks @rohitjavvadi.
 - Telegram: normalize legacy durable group retry targets before retry sends, polls, and pins so group retries keep using the real chat id. (#85656) Thanks @luoyanglang.
 - Agents/PDF: route MiniMax PDF fallback policy through plugin metadata so MiniMax uses text extraction instead of VLM image fallback. (#85590, fixes #85575) Thanks @neeravmakwana.
 - WebChat: summarize internal message-tool source replies so tool cards no longer duplicate the visible reply body. (#84773) Thanks @jason-allen-oneal.
