Add missing SyncValues class with UUID serializer

[Copilot]

Application failed on startup with NoClassDefFoundError: Could not initialize class dev.slne.surf.chat.core.common.util.SyncValues caused by missing UUID serializer in kotlinx.serialization. Error occurred during PreLoginChatTask when IgnoreListRepository.cacheIgnorelist attempted class initialization.

Changes

Created /surf-chat-core/src/main/kotlin/dev/slne/surf/chat/core/common/util/SyncValues.kt:

• UUIDSerializer: Custom KSerializer<UUID> that serializes UUIDs as strings. Includes error handling that wraps IllegalArgumentException in SerializationException with format expectations.

• SyncValues object: Provides serializersModule with contextual UUID serialization and pre-configured json instance for immediate use.

object UUIDSerializer : KSerializer<UUID> {
    override val descriptor = PrimitiveSerialDescriptor("UUID", PrimitiveKind.STRING)
    
    override fun serialize(encoder: Encoder, value: UUID) {
        encoder.encodeString(value.toString())
    }
    
    override fun deserialize(decoder: Decoder): UUID {
        val uuidString = decoder.decodeString()
        return try {
            UUID.fromString(uuidString)
        } catch (e: IllegalArgumentException) {
            throw SerializationException("Invalid UUID format: '$uuidString'", e)
        }
    }
}

Usage: Use SyncValues.json for serializing data with UUID fields, or include SyncValues.serializersModule in custom Json configurations.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
