feat(lua): enhance runtime environment with resilient module loading

Introduce robust Lua module deployment strategy that ensures proper library
availability across different system configurations. The implementation now
prioritizes Home Assistant's configuration directory for persistent storage,
with automatic failover to temporary locations when permission restrictions
occur. Additionally, the runtime now validates module dependencies during
initialization and provides clear diagnostic warnings for any loading failures.
