feat(pack): add Waystones and its compatibility addons

Adds Waystones plus two integrations that hook mods already in the pack:
Waystones: Sable (Create Aeronautics addon) and Xaero's Minimap & World
Map - Waystones Compatibility.

packwiz auto-resolved Balm as Waystones' required library; it was then
added explicitly as well, which was a no-op, so there is only one Balm
metafile.

Balm's Modrinth environment is client_or_server, which packwiz flags as
ambiguous ("one of these is unnecessary") and records as side = both.
That is the right call here: Balm is a library needed wherever Waystones
runs, and Waystones is client_and_server.

All four pinned versions are NeoForge 1.21.1 releases, and each jar's
sha512 was re-verified against its recorded hash.
