[codex] refresh plugin regression fixtures

Summary:
- Refresh plugin regression fixtures and test-support mocks for guarded network resolution, progress streaming windows, staged TTS output, QQBot STT, and CLI runner assertions.
- Resolve current-main conflicts in Discord, Google video, QQBot STT, and CLI runner tests without changing runtime code.

Verification:
- pnpm check:test-types
- pnpm vitest run $(git diff --name-only origin/main...HEAD)
- git diff --check
- GitHub CI passed, including Real behavior proof, auto-response, ClawSweeper dispatch, CodeQL, and full CI checks.
