Build dispatch was constructing its manifest without lookaheads, so the build dependency resolver missed transitive URL dependencies from workspace members referenced via build-system.requires.

Run LookaheadResolver first and pass the result into Manifest::with_lookaheads, matching the behavior the project resolver already uses.

Added a regression integration test that fails on main and passes with this change.

Closes #19074!

## Summary

Small follow-up to #19076. If a
lookahead URL has its own SHA, we need to include it in the acceptable
SHAs for that URL.

### [`v0.11.9`](https://github.com/astral-sh/uv/blob/HEAD/CHANGELOG.md#0119)

[Compare Source](astral-sh/uv@0.11.8...0.11.9)

Released on 2026-05-04.

This release includes a special release candidate for the next Python 3.14 patch release. Python 3.14 included a new garbage collection implementation, which reduced pause times but caused significant unexpected memory pressure in production environments. In 3.14.5 and 3.15, the previous garbage collection implementation will be restored.

We would greatly appreciate if you tested the 3.14.5rc1 version included in this release. The stable version is expected to be released soon and any feedback on potential issues would be helpful to the Python development team.

For more context, see the [announcement](https://discuss.python.org/t/reverting-the-incremental-gc-in-python-3-14-and-3-15/107014), [issue](python/cpython#148726), and [pull request](python/cpython#148720).
