Defer extension tool history materialization until first access ( #47035 ) ...
## Why
Extension tool calls eagerly copied and converted conversation history even when the tool never read it.
## What changed
Retain a shared invocation-time snapshot and defer conversion to raw response items until `ConversationHistory::items()` is called. Cache the result across clones with `LazyLock`, and keep debug formatting from triggering materialization. Release unrelated history metadata when capturing the shared items.
## Testing
Extend the extension executor test to verify that history first read after a later turn still reflects the invocation-time snapshot, in both legacy and paginated history modes. Update the history API test to check that shared items preserve their envelopes.
