Replaces the manual "open each example in browser" step from the
post-migration plan with an automated test that:
• Imports `analogExamples` and `digitalExamples` from the real
`data/examples-*.ts` modules — new gallery entries pick up the
test automatically.
• Uses the same `stripBrandPrefix` + board-filter logic that
production `loadExample.ts` uses, via the new shared helper
`utils/exampleToBuildNetlistInput.ts`. Single source of truth:
if the wokwi/velxio prefix rule ever changes, both production
and the smoke test track it.
• Runs each example through `solveInput` (Phase 1c F2 helper)
against the same ngspice WASM production uses.
`loadExample.ts` refactored to call `stripBrandPrefix` instead of
inlining the regex (two call sites converged on the helper).
Result against the gallery:
• 67/68 examples converge cleanly.
• 1 known regression: `an-opamp-follower` (LM358 follower) — the
same case `examples-analog-live.test.ts` already skips. Item
#2 (.op convergence helpers in NgSpiceWorkerAdapter) targets it.
The smoke test now serves as the safety net for the remaining
post-migration work — it'll flag if a future fix breaks examples
that converge today.
