+            val parts = jwt.split('.')
+            check(parts.size == 3) { "Invalid JWT" }
+
+            val payload = parts[1].decodeBase64String()


Make sure this works with base64-url encoding, and without padding. See discussion:
powersync-ja/powersync.dart#58 (review)

Alternatively, just remove getExpiryDate and decodeJwt for the alpha.

From ktor's implementation, it does look like they handle padding and byte masks, normalizing the input before decoding.

https://github.com/ktorio/ktor/blob/main/ktor-utils/common/src/io/ktor/util/Base64.kt

Looks like padding is fine, but I don't see anything handling base64url characters (uses - and _ instead of + and /).

This functionality is unlikely to be used much so it's not a massive blocker, but I'd prefer to remove it rather than have a broken implementation

Looks good from my side.
