fix(channels): skip empty progress drafts

 ### Fixes
 
 - Gateway/systemd: preserve operator-added secrets in the Gateway env file across re-stage while clearing OpenClaw-managed keys (such as `OPENCLAW_GATEWAY_TOKEN`) so a fresh staging value is never shadowed by a stale env-file copy; operator secrets are also retained when the state-dir `.env` is empty. Fixes #76860. Thanks @hclsys.
+- Slack/Matrix: avoid creating blank progress-draft messages when `streaming.progress.label=false` and progress tool lines are disabled. Thanks @vincentkoc.
 - QA/Matrix: keep the mock OpenAI tool-progress provider aligned with exact-marker Matrix prompts so the hardened live preview scenario still forces a deterministic read before final delivery. Thanks @vincentkoc.
 - OpenAI/Google Meet: wait for realtime voice `session.updated` before treating the bridge as connected, so Meet joins do not return with audio queued behind an unconfigured realtime session. Thanks @vincentkoc.
 - Plugins/catalog: merge official external catalog descriptors into partial package channel config metadata, so lagging WeCom/Yuanbao manifests keep their own schema while still exposing host-supplied labels and setup text. Thanks @vincentkoc.
