All six test/build scripts assumed a nested app/ package that
doesn't exist — the Flutter package lives at the repo root.
Removed every `cd app` and phantom path, consolidated the
redundant dart/flutter analyze passes in test.sh, and scoped
test_core.sh to core subsystem dirs so it no longer overlaps
with the full flutter test run.

Makefile grows targets for each test layer (test, test-a11y,
test-integration, test-e2e, test-all), the coverage + smoke-bundle
helpers, and the UI harness (ui-dev, ui-stop, ui-smoke). push-check
now runs `test + test-a11y` — fast pre-push gate under 90s.
ci/coverage.sh is renamed to ci/test_coverage.sh so it matches the
`test_*.sh` naming of the other layer scripts and sidesteps the
repo's `coverage.*` gitignore pattern (intended for coverage output
files like coverage.lcov, not scripts).
