fix(agents): align session lock hold budget with run timeouts

CHANGELOG.md

@@ -23,6 +23,7 @@ Docs: https://docs.openclaw.ai
 - Scripts/UI/Windows: fix `pnpm ui:*` spawn `EINVAL` failures by restoring shell-backed launch for `.cmd`/`.bat` runners, narrowing shell usage to launcher types that require it, and rejecting unsafe forwarded shell metacharacters in UI script args. (#18594)
 - Hooks/Session-memory: recover `/new` conversation summaries when session pointers are reset-path or missing `sessionFile`, and consistently prefer the newest `.jsonl.reset.*` transcript candidate for fallback extraction. (#18088)
 - Slack: restrict forwarded-attachment ingestion to explicit shared-message attachments and skip non-Slack forwarded `image_url` fetches, preventing non-forward attachment unfurls from polluting inbound agent context while preserving forwarded message handling.
+- Agents/Sessions: align session lock watchdog hold windows with run and compaction timeout budgets (plus grace), preventing valid long-running turns from being force-unlocked mid-run while still recovering hung lock owners. (#18060)
 - Cron/Heartbeat: canonicalize session-scoped reminder `sessionKey` routing and preserve explicit flat `sessionKey` cron tool inputs, preventing enqueue/wake namespace drift for session-targeted reminders. (#18637) Thanks @vignesh07.
 - OpenClawKit/iOS ChatUI: accept canonical session-key completion events for local pending runs and preserve message IDs across history refreshes, preventing stuck "thinking" state and message flicker after gateway replies. (#18165) Thanks @mbelinky.
 - iOS/Onboarding: add QR-first onboarding wizard with setup-code deep link support, pairing/auth issue guidance, and device-pair QR generation improvements for Telegram/Web/TUI fallback flows. (#18162) Thanks @mbelinky and @Marvae.
