feat(pack): add LambDynamicLights

Client-side NeoForge 1.21.1 dynamic lighting for held and placed light
sources. Modrinth reports server_side as unsupported, so packwiz writes
side = "client" and the jar stays off the server.

The Modrinth version metadata lists Fabric API as a required dependency,
but that entry is not loader-scoped. The NeoForge jar actually depends
only on its JarJar-bundled lambdynlights_runtime, so packwiz failing to
resolve Fabric API is expected and no fabric-api metafile is added.
