Heartbeat: allow suppressing tool warnings (#18497)

* Heartbeat: allow suppressing tool warnings

* Changelog: note heartbeat tool-warning suppression

CHANGELOG.md

@@ -27,6 +27,7 @@ Docs: https://docs.openclaw.ai
 - Telegram: prevent streaming final replies from being overwritten by later final/error payloads, and suppress fallback tool-error warnings when a recovered assistant answer already exists after tool calls. (#17883) Thanks @Marvae and @obviyus.
 - Memory/QMD: scope managed collection names per agent and precreate glob-backed collection directories before registration, preventing cross-agent collection clobbering and startup ENOENT failures in fresh workspaces. (#17194) Thanks @jonathanadams96.
 - Auto-reply/TTS: keep tool-result media delivery enabled in group chats and native command sessions (while still suppressing tool summary text) so `NO_REPLY` follow-ups do not drop successful TTS audio. (#17991) Thanks @zerone0x.
+- Heartbeat: allow suppressing tool error warning payloads during heartbeat runs via a new heartbeat config flag. (#18497) Thanks @thewilloftheshadow.
 - Cron: preserve per-job schedule-error isolation in post-run maintenance recompute so malformed sibling jobs no longer abort persistence of successful runs. (#17852) Thanks @pierreeurope.
 - CLI/Pairing: make `openclaw qr --remote` prefer `gateway.remote.url` over tailscale/public URL resolution and register the `openclaw clawbot qr` legacy alias path. (#18091)
 - CLI/QR: restore fail-fast validation for `openclaw qr --remote` when neither `gateway.remote.url` nor tailscale `serve`/`funnel` is configured, preventing unusable remote pairing QR flows. (#18166) Thanks @mbelinky.

 - `every`: duration string (ms/s/m/h). Default: `30m`.
+- `suppressToolErrorWarnings`: when true, suppresses tool error warning payloads during heartbeat runs.
 - Per-agent: set `agents.list[].heartbeat`. When any agent defines `heartbeat`, **only those agents** run heartbeats.
 - Heartbeats run full agent turns — shorter intervals burn more tokens.

 - `accountId`: optional account id for multi-account channels. When `target: "last"`, the account id applies to the resolved last channel if it supports accounts; otherwise it is ignored. If the account id does not match a configured account for the resolved channel, delivery is skipped.
 - `prompt`: overrides the default prompt body (not merged).
 - `ackMaxChars`: max chars allowed after `HEARTBEAT_OK` before delivery.
