[Bug]: examples/openclaw-plugin/index.ts missing withTimeout protection (same as #673)

[Meskjei]

Bug Description

PR #688 fixed the auto-recall timeout issue in examples/openclaw-memory-plugin/index.ts by wrapping the recall logic with withTimeout(). However, the plugin code was later moved to examples/openclaw-plugin/index.ts, and the fix was not synchronized to the new location.

The current code in examples/openclaw-plugin/index.ts (main branch) still has the same bug:

• autoRecallTimeoutMs = 5_000 is defined but never used
• withTimeout is imported but not called in the auto-recall path
• If the OpenViking HTTP calls hang (e.g., during transient connection issues), the before_prompt_build hook blocks indefinitely, causing total agent silence

Steps to Reproduce

1. Use the plugin from examples/openclaw-plugin/ directory
2. Configure with autoRecall: true
3. Have OpenViking server in a transient state (e.g., shortly after gateway restart)
4. Send a message to the agent
5. Agent hangs silently at before_prompt_build hook

Expected Behavior

If auto-recall does not complete within autoRecallTimeoutMs (5 seconds), the hook should:

• Time out gracefully
• Log a warning
• Allow the agent to start without memory context

Actual Behavior

The hook blocks indefinitely. No response is ever sent to the user.

Root Cause

PR #688 applied the fix to examples/openclaw-memory-plugin/index.ts, but the plugin was later refactored/moved to examples/openclaw-plugin/index.ts without carrying over the timeout protection.

Proposed Fix

Apply the same fix from PR #688 to examples/openclaw-plugin/index.ts:

// Current code (line ~439):
if (cfg.autoRecall && queryText.length >= 5) {
  const precheck = await quickRecallPrecheck(...);
  if (!precheck.ok) {
    // skip
  } else {
    try {
      // ← No timeout protection here
      const candidateLimit = ...
      const [userSettled, agentSettled] = await Promise.allSettled([...]);
      // ... more awaits
    } catch (err) {
      api.logger.warn(...);
    }
  }
}

// Should be:
if (cfg.autoRecall && queryText.length >= 5) {
  const precheck = await quickRecallPrecheck(...);
  if (!precheck.ok) {
    // skip
  } else {
    try {
      await withTimeout(
        (async () => {
          // ← Wrap entire recall logic in IIFE
          const candidateLimit = ...
          const [userSettled, agentSettled] = await Promise.allSettled([...]);
          // ... more awaits
        })(),
        autoRecallTimeoutMs,
        `openviking: auto-recall timed out after ${autoRecallTimeoutMs}ms`,
      );
    } catch (err) {
      api.logger.warn(`openviking: auto-recall failed or timed out: ${String(err)}`);
    }
  }
}

Additional Context

• This is the same bug as [Bug]: memory-openviking plugin before_agent_start auto-recall hangs indefinitely, causing total silent agent failure #673, but affecting the refactored plugin directory
• Impact: Critical — any transient connection issue causes complete, permanent agent silence
• Workaround: Set autoRecall: false in plugin config
