### What problem does this PR solve?
Issue Number: None
Related PR: #62946
Problem Summary: Schema change and rollup jobs exposed shadow indexes to
load planning before reserving their watershed transaction boundary. A
transaction could therefore miss the shadow index while being ordered after the
watershed, leaving a rowset version gap that the alter job would not wait for.
Reserve the boundary under the same table write lock used to publish the shadow
metadata in local and cloud jobs, and keep schema-change jobs pending when the
second stability check aborts publication.
