This commit configures Hard Lounge as a dedicated webchat client for SuperNETs IRC, requiring only a nickname to connect. - Set `public: true` to enable public mode (no user accounts required) - Set `lockNetwork: true` to lock connections to irc.supernets.org only Users will automatically connect to irc.supernets.org:6697 (TLS) and join #superbowl upon entering a nickname. - Added simplified connect form for public + lockNetwork mode - Form now shows only the nickname field when both settings are enabled - Hidden fields: server, port, TLS, username, realname, channels, leave message, authentication options - Added CSS styling for proper spacing on simplified form - Pinned to Node 20 Alpine (from lts-alpine) for compatibility - Added py3-setuptools to fix distutils module error with Python 3.12 - Fixed file ownership with --chown=node:node on COPY commands - Moved USER node directive after COPY to fix permission issues - Pre-create /var/opt/hardlounge directory with correct ownership
