/**
 * Collect properties with a common prefix into a single object.
 * Useful for gathering related properties from node metadata.
 *
 * For example, given metadata with:
 * - sound_volume: 0.5
 * - sound_loop: true
 * - sound_spatial: false
 *
 * Calling collectPrefixedProperties(metadata, 'sound') returns:
 * { volume: 0.5, loop: true, spatial: false }
 *
 * @param metadata - The node metadata to search
 * @param prefix - The prefix to match (without trailing underscore)
 * @returns Object with sub-properties (prefix and underscore removed from keys)
