add app test suite — unit, widget, golden, a11y (168 tests)

Four layers under app/test/: * kernel/, extension/ — unit tests for every kernel service and the extension contract. i18n fallback chain gets the full matrix (exact/lang/default/placeholder, namespace isolation, unknown namespace, interpolation). Theme resolver and extension-manager topo sort covered. * widgets/, builtin/ — widget tests for every primitive and each Tier 0 built-in. Assertions reach into the Semantics node so a missing label fails structurally, not visually. * goldens/ — Alchemist + Ahem font for cross-platform pixel stability; primitives only (button, tab bar, icon set). No goldens for compositions — they'd churn through every tier. * a11y/ — contract-level gate: semantic coverage walks the built-in catalogue, contrast walks every token pair in every bundled theme against WCAG-AA thresholds (catches real regressions: the first run caught `tab.inactive_text` at 2.81 in summer-night), i18n coverage asserts every referenced key exists in its catalog (exists-in-map, not "key == value" — too ambiguous for keys that happen to equal their translation). Helpers under helpers/: `KernelFixture.create()` boots a KernelServices with in-memory stores + a FakeDaemonClient (no socket, drivable connected-state), `widget_harness` wraps a widget in the minimum tree that resolves theme + i18n.
