fix(heartbeat): align response tool prompts (#76458)

* fix(heartbeat): align response tool prompts

* docs(changelog): credit heartbeat prompt fix

CHANGELOG.md

@@ -95,6 +95,7 @@ Docs: https://docs.openclaw.ai
 - Gateway: preserve stack diagnostics when `chat.send` or agent attachment parsing/staging fails, improving image-send failure triage. Refs #63432. (#75135) Thanks @keen0206.
 - Agents/idle-timeout: add a cost-runaway breaker to the outer embedded-run retry loop that halts further attempts after 5 consecutive idle timeouts without completed model progress, so a wedged provider can no longer fan paid model calls out across the same run; completed text or tool-call progress resets the breaker, but partial tool-argument token dribbles do not. Fixes #76293. Thanks @ThePuma312.
 - Heartbeats/Codex: stop sending the legacy `HEARTBEAT_OK` prompt instruction when heartbeat turns have the structured `heartbeat_respond` tool, while keeping the text sentinel for legacy automatic heartbeat replies. Thanks @pashpashpash.
+- Heartbeats/Codex: keep structured heartbeat prompts aligned with actual `heartbeat_respond` tool availability and keep tool-disabled commitment check-ins on the legacy ack path. Thanks @pashpashpash and @vincentkoc.
 - Agent runtimes: fail explicit plugin runtime selections honestly when the requested harness is unavailable instead of silently falling back to the embedded PI runtime. Thanks @pashpashpash.
 - Maintainer workflow: push prepared PR heads through GitHub's verified commit API by default and require an explicit override before git-protocol pushes can publish unsigned commits. Thanks @BunsDev.
 - Feishu: resolve setup/status probes through the selected/default account so multi-account configs with account-scoped app credentials show as configured and probeable. Fixes #72930. Thanks @brokemac79.
