[BUG] TaskCreate batch calls display tasks in random order instead of creation order

What's Wrong?
When calling multiple TaskCreate tools in parallel within a single response, the resulting task list displays tasks in a seemingly random order instead of the order they were created in.

For example, creating 11 tasks in order (step 1 through step 11), the returned task IDs and display order are jumbled:

• Task #145: step 1
• Task #144: step 2
• Task #141: step 3
• Task #143: step 4
• Task #140: step 5
• Task #142: step 6

The IDs are not sequential and the display order does not match creation order.

What Should Happen?
Tasks created in a batch should be assigned sequential IDs and displayed in creation order (i.e., the order the TaskCreate calls were made).

Steps to Reproduce

1. In a single response, call TaskCreate 6+ times in parallel
2. Observe the returned task IDs are not sequential
3. Call TaskList - tasks are displayed in random order, not creation order
