Owen Lin dc60dadce6 Enforce single-writer ownership for all thread histories (#36389) ...

## Why

Legacy thread histories did not use the cross-process writer ownership guard already applied to paginated histories.

## What changed

- Acquire and retain a writer lock whenever a legacy or paginated thread is created or resumed.
- Apply the same ownership checks when archiving or deleting either history mode.
- Release ownership when initialization fails or the active thread shuts down, allowing another process to resume it.

## Testing

- Cover competing create and resume operations for both history modes.
- Cover archive and deletion conflicts for legacy and paginated descendants.
