fix #84745: scope Google preview model normalization to Google providers only (#84762)

Summary:
- The branch scopes config-time Google Gemini preview model normalization to Google providers or nested `google/` proxy suffixes, adds model-picker regression coverage, and adds a changelog entry.
- Reproducibility: yes. by source inspection. Current main sends every provider suffix through the Google prev ... i-3-flash` deterministically becomes `litellm/gemini-3-flash-preview`; I did not run a live cron preflight.

CHANGELOG.md

@@ -24,6 +24,7 @@ Docs: https://docs.openclaw.ai
 - Docker: prune package-excluded plugin source workspaces and dependency closures so runtime images do not keep packages for plugins that were not opted in.
 - Providers/Ollama: treat Docker/OrbStack host aliases as local Ollama endpoints so `ollama-local` marker auth works when OpenClaw runs inside a VM/container and Ollama runs on the host. Fixes #84875.
 - QA-Lab: keep explicitly searchable/deferred OpenClaw dynamic tool rows report-only by default so tool-coverage gates do not treat mock discovery gaps as hard product failures. (#80319) Thanks @100yenadmin.
+- Agents/config: keep non-Google provider model refs from being rewritten by Google Gemini preview-id normalization. (#84762) Thanks @zhangguiping-xydt.
 - Agents: cap heartbeat model bleed context hints by the stored session window when runtime model metadata is unavailable, so overflow recovery advice does not suggest a larger window than the active session actually has.
 - Control UI/Web Push: use `https://openclaw.ai` as the generated default VAPID subject instead of the old localhost mailbox so iOS PWA push setup uses an Apple-acceptable subject when `OPENCLAW_VAPID_SUBJECT` is unset. Fixes #83134. (#83317) Thanks @IWhatsskill.
 - Agents/Pi: keep embedded session transcript writes from tripping false takeover detection after packaged npm onboarding agent turns.
