Module indexes 

Secondary LMDB indexes for O(log n) lookups.

Four index sub-databases:

• idx_content_hash: {galaxy}:{hash} → UUID (O(1) dedup)
• idx_tags: {galaxy}:{tag} → UUID (DUP_SORT, tag-based queries)
• idx_importance: {galaxy}:{f32_be} → UUID (DUP_SORT, range queries)
• idx_temporal: {galaxy}:{i64_be} → UUID (DUP_SORT, time-range queries)

Keys are raw bytes: galaxy_db_name + 0x00 + value_bytes. The null separator ensures galaxy-scoped sorting.
