/**
* Gets existing value from Map or lazily creates it if missing.
*
* Implements the lazy initialization pattern: returns existing value if key
* exists, otherwise calls generator function to create new value, stores it,
* and returns it. Ensures generator is only called when necessary, avoiding
* wasteful computation.
*
* Used throughout AutoBE for caching event listeners, validation state, and
* other expensive-to-create objects that should be initialized on first
* access.
*
* @param dict Map to query and potentially update
* @param key Key to look up or create
* @param generator Function to create value if key doesn't exist
* @returns Existing or newly created value
