Release 0.3.0

site.yaml's hero is now plain | module, where module names a
JavaScript file the content repo ships (mount(container) -> handle
with stop()). Portal serves content assets same-origin at
/site/<path> (Gitea raw sends no CORS headers), starts the module at
HTML parse time, adopts it on hydration, mounts fresh via the inline
script's __mountHero on client-side navigation, and stops it on
leave. The YES canvas (yes.js) and the gesture hero mode leave the
engine - uhhm/questions ships YES as its hero.js, redoal/questions
ships a sine-swings band. Gesture form canvas no longer balloons after
a stroke: the wrap's aspect-ratio reservation is scoped to :empty
(pre-mount) so it can't turn echo-strip height into width inside the
flex field.
