Preserve the sticky-bottom follow invariant across streamed Dev Server and System Controls output.
- Track pinned-bottom state synchronously for rebuild and system-log streams.
- Follow in-place Dev Server transcript mutations only while the reader is pinned.
- Cover manual unsnapping, stream growth, and re-pinning behavior.
- Add a patch changeset for live-log scrolling.
