Merge master 0fdadce5189dcf13a00c2ed8293be95b9bb29c2c into the reviewed
Session V4 integration base. Preserve its V4 persistence and direct-catalog
subagent navigation while carrying forward current UI controls, decorative
icons, Desktop signing/runtime changes, and upstream tests.
Resolve lineage conflicts by retaining interaction-time catalog authority,
known-leaf handling and row order together with the shared status icons.
Keep both Desktop shell-routing regressions and one production route; master
now includes the route repair previously carried by this integration branch.
The full build, 41 documentation gates, two Desktop shell tests and 34 focused
Client lineage tests pass. Further built Web and packaging checks precede
publication. Preserve this pinned merge checkpoint before taking a newer
master tip, and propagate it through the reorganized feature stack.
