Client likes, replies, poll options, and poll votes now embed the referenced txid in little-endian wire order, matching the indexer's byte reversal. Add a psf-memo-db repair library and CLI that rewrites byte-reversed references in likes, postParents, pollOptions, and pollVotes and rebuilds the postLikes and postChildren indexes, leaving correct and unknown references untouched and staying idempotent. By coder.

Unit tests for the Memo like wire encoding.
|
|
|
|
A like action embeds the liked post's transaction txid as 32 raw bytes in
|
|
little-endian wire order: the reverse of the 64-character display txid. The
|
|
indexer reverses those bytes back into display order, so the client must
|
|
reverse before embedding.
