test(kicad): timer-park repro lever — deterministic concurrent-Asyncify window

Browse source 
kicadTestArmTimerPark(delayMs, parkMs): a one-shot wxTimer whose Notify()
emscripten_sleep()s, entering through the exact GAL-refresh-timer path
(emscripten_async_call → TimerCallbackFunc::Run → dispatch guard → Notify) —
the fresh-entry-that-parks the prod board-load trap family needs. Pollable
kicadTestTimerParkState(); inert unless armed. Registered beside
kicadTestSetOpenPark in pcbnew + the merged kicad_editor image.

tests/kicad/timer-park-repro.spec.ts drives four escalating cycles (park
only, 2× + fiber hammering, + 256MB heap growth mid-park) and asserts the
runtime survives every rewind AND that the [wx-asyncify] diagnostics observed
the window — engagement is asserted, so a run where the lever never created
the overlap cannot pass vacuously.

Result so far (docs/features/async/15-timer-park-repro.md): GREEN through
both rounds — genuine double-parks, live currData cross-restores, fiber
swaps, and mid-park heap growth are all handled by the shim + runtime. The
prod trap needs an ingredient this window still lacks (ranked in the doc);
the spec stays as the regression gate for whatever the eventual fix is.
