fix(deepseek): expose v4 thinking profile in policy surface

CHANGELOG.md

@@ -63,6 +63,7 @@ Docs: https://docs.openclaw.ai
 - Web search: scope explicit bundled `web_search` provider runtime loading through manifest ownership, so selecting DuckDuckGo/Gemini/etc. does not import unrelated bundled providers or log their optional dependency failures. Thanks @vincentkoc.
 - Plugins/discovery: demote the source-only TypeScript runtime check on already-installed `origin: "global"` plugin packages from a config-blocking error to a warning and let the runtime fall through to the TypeScript source via jiti, so a single broken installed package no longer blocks `plugins install` for unrelated plugins; install-time rejection of newly-installed source-only packages is unchanged. Thanks @romneyda.
 - Providers/OpenAI Codex: stop the OAuth progress spinner before showing the manual redirect paste prompt, so callback timeouts do not spam `Browser callback did not finish` across terminals.
+- Providers/DeepSeek: expose DeepSeek V4 `xhigh` and `max` thinking levels through the lightweight provider-policy surface, so Control UI `/think` pickers keep showing the max reasoning options when the runtime plugin registry is not active. Fixes #77139. Thanks @bittoby.
 - Release/beta smoke: resolve the dispatched Telegram beta E2E run from `gh run list` when `gh workflow run` returns no run URL, so the maintainer helper does not fail immediately after dispatch. Thanks @vincentkoc.
 - Media/images: keep HEIC/HEIF attachments fail-closed when optional Sharp conversion is unavailable instead of sending originals that still need conversion. Thanks @vincentkoc.
 - Google Meet: fork the caller's current agent transcript into agent-mode meeting consultant sessions, so Meet replies inherit the context from the tool call that joined the meeting.
