fix: stop denied exec followups (#85194)

Stops denied exec approvals from feeding agent follow-up work, suppresses node `exec.denied` wakeups, adds Chinese stop phrases to abort handling, and documents terminal denial behavior.

Fixes #69386.

 ### Fixes
 
 - Gateway CLI: surface local post-challenge connect assembly failures immediately instead of waiting for the wrapper timeout. Fixes #68944. (#85253) Thanks @samzong.
+- Agents/exec: treat denied exec approvals as terminal instead of feeding them back into agent follow-up work, and recognize Chinese stop phrases in abort handling. Fixes #69386. (#85194) Thanks @samzong.
 - Codex app-server: reject command overrides that embed Node or package-manager arguments and point users to `appServer.args`, so Windows startup avoids shell parsing failures. (#84417) Thanks @TurboTheTurtle.
 - Agents/Copilot: drop unsafe GitHub Copilot Responses reasoning replay items before send so Telegram direct sessions no longer fail on overlong replay IDs. Fixes #85197. (#85198) Thanks @galiniliev.
 - UI: add accessible tooltips to the topbar color-mode buttons so System, Light, and Dark choices are labeled on hover and focus. (#85227) Thanks @amknight.

 ## Denied approval behavior
 
-When an async exec approval is denied, OpenClaw prevents the agent from

-The denial reason is passed with explicit guidance that no command output

+When an async exec approval is denied, OpenClaw treats the request as terminal.
