Abhinav aa88a0333c Preserve tool output truncation budgets across resume and fork (#44248) ...

## Why

Replaying tool outputs under a different model can expand or shrink the history shown to the model if truncation uses the new model's budget.

## What changed

Save the originating history truncation budget on function and custom tool outputs and reuse it during replay, preserving existing tool-specific overrides. Include the existing 20% serialization allowance once, before converting byte budgets to tokens.

Rename the metadata field to `history_truncation_token_limit` while retaining `fallback_token_limit_override` as its serialized name for compatibility.

## Testing

Add regression coverage for resume and fork with different model budgets, including custom tool outputs. Extend unit coverage for existing overrides and byte-budget conversion.
