html_generator gains a standalone flag (USCG_STANDALONE) and escapes "</" in
the inlined manifest. New logic_standalone.js (loaded last) replaces every
parent-frame dependency: own ComfyUI websocket re-dispatching the bridge's
message shapes (session filter, id dedupe, backoff, resync on resume),
Fullscreen API, URL kept on the shown session, GENERATE NEW via
POST /config_tester/run, and an openStandalone() header button for the node
iframe. Lightbox gets modalNav/toggleModalFavorite/rejectModalItem helpers
and an action bar element (styled in the next commit).
