PR #78021: fix(taskflow): ensure endedAt >= updatedAt in finishFlow and failFlow

Description (problem / solution / changelog)

Problem

openclaw tasks audit reports inconsistent_timestamps warnings on succeeded TaskFlows: endedAt is earlier than updatedAt.

Root Cause

finishFlow and failFlow in task-flow-registry.ts accept caller-supplied endedAt and updatedAt without validating their order. If the caller passes endedAt < updatedAt, the invalid state is written directly to the record.

Fix

Add Math.max(endedAt, updatedAt) guard in both finishFlow and failFlow before writing to the patch, ensuring endedAt is never earlier than updatedAt.

const endedAt = params.endedAt ?? params.updatedAt ?? Date.now();
const updatedAt = params.updatedAt ?? endedAt;
const safeEndedAt = Math.max(endedAt, updatedAt);

Closes #78019

Real behavior proof

Behavior addressed

openclaw tasks audit reports inconsistent_timestamps on succeeded TaskFlows where endedAt is earlier than updatedAt. Observed 7 warnings on OpenClaw 2026.5.4.

Real environment tested

• OpenClaw 2026.5.4 (325df3e)
• macOS 26.4.1 (arm64)
• Node.js 24.15.0

New test case added: verifies that finishFlow and failFlow produce endedAt >= updatedAt when caller passes endedAt < updatedAt.

Observed result after the patch

All 6 tests pass including the new regression test. The Math.max guard ensures safeEndedAt >= updatedAt before writing to the record.

What was not tested

End-to-end verification that openclaw tasks audit reports 0 warnings after patched build is deployed — this requires a live gateway running the patched version.
