test v1.43.2: smokes that can fail, in CI, and an honest TESTING.md

T1: demo/serve.mjs exports check/checkAll/finish — all 48 smokes now
assert named facts and exit non-zero on a mismatch or an uncaught
in-card exception (verified by breaking the kiosk guard on purpose).
Informational values were frozen from a v1.43.1 run and cross-read
against the source; timings assert budgets, not exact numbers.

T2: new CI job 'smoke' gated on 'frontend', builds a FRESH bundle
before running (the committed demo/srv/assets copy is a snapshot) and
uploads per-file logs on failure.

T3: [auto] now means 'a named failing check exists' and each line names
it (43 lines); 72 aspirational markers honestly downgraded to [manual].
Fixed the 'ZERO edit buttons' contradiction (wrong since v1.30.1) and
the opening-click line (true again since v1.43.1).

Three smokes carried pre-v1.39.0/v1.25 expectations and were testing
old behaviour: tap defaults for lights, card-wide tap action, label drag
requiring plan mode.

DEVELOPMENT.md documents the harness contract.
