Space is now the alternate jump key (was shoot). Web shell shows game controls by default and hides editor UI unless localStorage.show_editor is set to 'true'. The E key and ?edit URL are blocked when the editor is not enabled. Also fix Makefile to track web/shell.html as a WASM link dependency so shell changes trigger a rebuild.
