on_close

std::function<void()> MayaFlux::Portal::Forma::SurfaceConfig::on_close

Runs in addition to, never instead of, the built-in close handling.

Setting this forces should_detach_on_close() true regardless of detach_on_close, so supplying a hook can never silently lose the window-release cleanup.

Context::on_close is a single slot per id, and the last write wins, so a bare replacement field here would silently clobber Surface's own close handler on first use. This field exists so that cannot happen.
