ChaCha20Core.chaCha20Xor:
- Parse key/nonce once into initial state, reuse across blocks
- XOR at word level (4 bytes at a time) instead of byte-by-byte
- Reuse working IntArray across blocks instead of allocating per block
XChaCha20Poly1305:
- Add hChaCha20FromNonce24 to avoid nonce copyOfRange(0,16) allocation
- Add chaCha20PolyKey to generate only 32 bytes instead of full 64-byte block
- Use single result array instead of ciphertext + tag concatenation
Benchmark (98-byte padded message, JVM):
Before: encrypt 2286 ns/op, decrypt 2062 ns/op
After: encrypt 1544 ns/op, decrypt 341 ns/op

JesterContent fields version, fen, and history were omitted from
serialized JSON because kotlinx.serialization skips default values.
Jester's isStartGameEvent checks arrayEquals(json.history, []) which
fails when the field is absent (undefined !== []).
Added @EncodeDefault to version, fen, and history so they are always
included in the JSON output regardless of value.

jester.nyo.dev uses offchain.pub as one of its relays. Adding it gives
us 2 shared relays (relay.damus.io + offchain.pub) instead of 1,
improving challenge visibility between Amethyst and Jester clients.

ChessEngine.makeMove() now normalizes SAN notation before passing to
chesslib, fixing games against jester.nyo.dev and other clients that
use different notation:
- Castling: 0-0 → O-O, 0-0-0 → O-O-O (zeros to letters)
- Annotations: strips !, ?, !!, ??, !?, ?! suffixes
Previously, chesslib rejected 0-0/0-0-0 causing ChessStateReconstructor
to mark games as desynced and skip remaining moves. Games appeared
permanently stuck, even after app restart.
Also fixes discoverUserGames() silently dropping games classified as
spectator — now adds them to spectatingGames instead.
23 new interop tests covering SAN variants, reconstruction, spectator
detection, and missing start event handling.
