Master gained a web-search e2e scenario that calls connectFreshWorkspace
with the pre-change one-argument signature, which fails to compile against
the test-merge commit CI builds. Give it the scaffold's workspace root like
every other scenario.
Master also gained the first-run welcome notice. The shared scaffold
acknowledges it before boot, but the W5 smoke spawns its own server against
a fresh $DSH_HOME, so its overlay owns pointer events and swallows the
first click on the workspace chip; the scenario now dismisses the notice
first. The notice is anchored structurally because this spec belongs to the
client TypeScript program, which does not reference the package owning its
copy.
