fix: use configured checkpoint timeout for wait warning

[ThanhNguyxn]

Summary

Fixes #10657

The checkpoint initialization warning was using a hardcoded 5-second value (WARNING_THRESHOLD_MS / 1000) for the timeout parameter in the warning message, regardless of the user's actual configured checkpoint timeout.

This PR updates the code to use task.checkpointTimeout for the warning message parameter, ensuring the message correctly reflects the configured timeout (e.g., "taking longer than 15 seconds...").

Changes

• Modified src/core/checkpoints/index.ts: Pass task.checkpointTimeout instead of hardcoded 5s to sendCheckpointInitWarn.
• Updated src/core/checkpoints/__tests__/checkpoint.test.ts: Updated test case to verify that the warning message receives the configured timeout value.

Testing

1. Verified closely with the existing test suite.
2. The should send warning message when initialization is slow test case now explicitly checks for matching task.checkpointTimeout.

Important

Fixes hardcoded timeout in checkpoint warning message to use task.checkpointTimeout in index.ts.

• Behavior:
  • sendCheckpointInitWarn in index.ts now uses task.checkpointTimeout instead of a hardcoded 5s for warning messages.
  • Updates warning message to reflect configured timeout (e.g., "taking longer than 15 seconds...").
• Testing:
  • Updated test in checkpoint.test.ts to verify warning message uses task.checkpointTimeout.
  • Test case should send warning message when initialization is slow checks for correct timeout value in warning message.

Review complete. No issues found. The fix correctly uses task.checkpointTimeout instead of the hardcoded 5-second value for the warning message, making it consistent with how INIT_TIMEOUT already handles this.
