fix(mattermost): suppress draft progress chatter

CHANGELOG.md

@@ -62,6 +62,7 @@ Docs: https://docs.openclaw.ai
 - Discord/Slack/Mattermost: align draft preview tool-progress config help with the runtime behavior that hides interim tool updates when `streaming.preview.toolProgress` is false. Thanks @vincentkoc.
 - Feishu: use the shared channel progress formatter for streaming-card tool status lines, including raw command/detail output and message-tool filtering. Thanks @vincentkoc.
 - Mattermost: use the shared progress draft formatter for tool status previews, including raw command/detail output when `agents.defaults.toolProgressDetail: "raw"` is enabled. Thanks @vincentkoc.
+- Mattermost: suppress standalone default tool-progress messages while draft previews are active, including when draft tool lines are disabled. Thanks @vincentkoc.
 - OpenAI Codex: honor `auth.order.openai-codex` when starting app-server clients without an explicit auth profile, so status/model probes and implicit startup use the configured Codex account instead of falling back to the default profile. Thanks @vincentkoc.
 - OpenAI Codex: let SSRF-guarded provider requests inherit OpenClaw's undici IPv4/IPv6 fallback policy, so ChatGPT-backed Codex runs recover on IPv4-working hosts when DNS still returns unreachable IPv6 addresses. Fixes #76857. Thanks @jplavoiemtl and @SymbolStar.
 - 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.
