+-- Comprehensive storage optimization: Normalize DIDs, optimize CIDs, use FKs to records
+--
+-- This migration optimizes ALL major tables in one pass:
+-- - records: Remove at_uri, use actor_id + collection ENUM + rkey
+-- - likes: Replace did + subject + subject_cid with actor_id + subject_record_id
+-- - reposts: Replace did + post + post_cid with actor_id + post_record_id
+-- - posts: Replace did + parent/root URIs with actor_id + parent/root_record_id, strip CID headers
+-- - follows: Replace did with actor_id
+-- - blocks: Replace did with actor_id
+-- - notifications: Replace DIDs with actor_ids, strip CID header
