Ruslan Nigmatullin 77cbcdb4a6 Preserve thread-local model ID state across replay and compaction (#60942) ...

## What changed

- Initialize item and context-window ID generators per thread, reuse the stored window on resume, and give history reconstruction a separate item generator.
- Recover item ordinals from checkpoint replacement history, guardian history, and retained context without lowering the cursor established by earlier records.
- Stamp compaction resume metadata with the next item ordinal in append order, tracking the cursor in local and in-memory thread stores.

## Testing

Extend the history ordinal test to verify that a checkpoint records the cursor at its position in a batch, excluding later allocations.
