Ported from nanocomponent 6.6.0 and on-load 3.4.1 (MIT) with attribution:
render/update/morph lifecycle, proxy nodes with isSameNode identity, and
the MutationObserver-driven load/unload hooks. This class is the intended
island/hydration boundary for later phases. @choojs/core exposes ./timing
as a subpath for the instrumentation calls.
