## What's going on
The stacked pull requests are blocked by GitHub's stack merge flow. This
gives the full remaining search ranking change set one PR against
`main`.
## The plan
- Consolidates the open work from #49190, #49191, #49194, #49195,
#49197, #49246, #49247, and #49249.
- Keeps the existing stack unchanged while this PR provides an alternate
merge path.
