Merge diag/textgate-build-marker: console build tag

Loading a workflow does not re-fetch extension JS, and aiohttp serves
web/*.js with only Last-Modified (no no-store), so an open tab can keep
running a cached old text_gate.js. Log a build tag on setup so we can
tell from the devtools console whether the persistence/weighting build
is actually loaded.
