fix theme picker integration test; one bake for build-time facts (T-116)

The test was awaiting services.commands.execute('theme.pick') whose
Future doesn't complete until the dialog is dismissed — deadlock.
Fire-and-forget around pumpAndSettle, then tap Cancel, then await
the original future. Also tear the widget tree down before
services.dispose() so listening widgets unsubscribe first.

Pre-existing layout overflow in the welcome _StatusLine surfaced
when running the test at narrower viewports. Switched to a whole-
row FittedBox(scaleDown) — uniform shrink on narrow screens, no-op
at standard widths.

User flagged the hardcoded 'clide 2.0.0-dev' string. Replaced with
one generated lib/src/build_info.g.dart (gitignored, regenerated
by `make gen-build-info` from pubspec.yaml + git short SHA + UTC
clock). The same target re-syncs assets/licenses.yaml self.version
in place — no second source. Every make build/run/test depends on
it implicitly. Welcome status line now reads `clideVersion`. Stale
fontSize literals in welcome_view swept to typography constants;
clideFontMeta=13, clideFontDialogTitle=16, clideFontWelcomeBanner=52
added to fill gaps in the scale.
