Owen Lin 2f02d8461d Support update-boundary paging across forked thread histories (#59793) ...

## Why

Item reads with an update boundary previously rejected forked thread histories and only supported an exclusive lower bound on update ordinals.

## What changed

- Add `before_updated_at_ordinal` as an exclusive upper bound, mutually exclusive with `after_updated_at_ordinal`.
- Allow update-filtered and update-ordered item reads across parent and child segments, applying segment bounds and preserving cursor pagination in both directions.
- Require an update boundary for update-order sorting and reject either boundary when using an item anchor or item-ID filtering.

## Testing

Extend thread-store tests to cover upper-bound filtering, descending cursor pagination, forward and backward paging across forked lineages, mutually exclusive boundaries, and ordinals outside SQLite's integer range.
