Support direct params format in fetchCollection

Allow both calling styles for fetchCollection:
- col('tasks', { params: { status: 'active' } })  // explicit params key
- col('tasks', { status: 'active' })              // direct params format

When opts.params is undefined but opts has keys other than 'force' and 'params',
the opts object (minus force) is treated as params directly.

This provides a more intuitive API while maintaining backward compatibility.
