v1.3.0

[1.3.0] - Minecraft 1.21.8 support and three new abilities

Added

• Minecraft 1.21.8 support — new fabric-1.21.8 and neoforge-1.21.8 modules, backed by a
  new common-1.21.8 implementation. 1.21.8 predates Mojang's ResourceLocation→Identifier
  rename (that lands at 1.21.9+), so it needed its own port rather than reusing 1.21.1 or
  1.21.11 outright — see AGENT.md's API-notes table for the exact divergences (particle option
  types, command permission API, the AbstractArrow package). Every existing item, ability, and
  system behaves identically on 1.21.8 as on 1.21.11.
• geyser_burst (Water) — a raycast counterpart to tidal_surge: erupt a geyser at a
  targeted point up to range blocks away, launching everything within radius upward, dealing
  light magic damage, and applying SOAKED. Good for launching a cluster off a ledge or setting up
  a storm_chain follow-up. See examples/items/tidewaker_trident.json.
• ember_burst (Fire) — on kill, a small fire nova erupts at the corpse and ignites nearby
  enemies. A follow-up payoff for on_kill weapons — chain kills to clear a cluster.
• soul_lash (Soul) — spends one stored soul per hit (instead of draining the whole pool like
  soul_surge) for a smaller, repeatable burst of bonus magic damage plus lifesteal. Requires
  soulCapacity on the item; does nothing and costs no cooldown when the item holds too few
  souls. See examples/items/soulforged_scythe.json.
