Almanac Core

v0.0.0-beta.1 - Spell, ritual, research node & relic codecs

First versioned build of Almanac Core, the content-as-data library behind Majestic.

Added

• Codecs: SpellDefinition, RitualDefinition (item-or-tag inputs), ResearchNodeDefinition and RelicDefinition — full JSON schemas for datapack-driven content.
• Loaders: a reload listener per kind, feeding a shared in-memory registry that survives partial reloads without wiping unrelated content.
• Sync: the full loaded content set is pushed to clients on login and on every datapack reload.
• /almanaccore status debug command (counts + ids per kind).
• Wired Astral Core as a real dependency.

Fixed

• A shared clear() wiped all four content registries on any single reload — now per-kind.
• The ritual input's union Codec (item xor tag) had an empty encode(), which would have corrupted server→client sync as soon as real ritual data existed — implemented properly.
• runs.data used clientData(), invalid on net.neoforged.moddev 2.0.142 — fixed to data().

Library mod, ships no content by itself. Install it because another mod (starting with Majestic) requires it. JEI stays a stub for now; the Vellumli guide bridge doesn't exist yet.
