Ars Zero

Added

- Added the **Conjure Arcane Shield** tier-two Manipulation glyph, adapted for 1.21.1 from [PR #34](https://github.com/zeroregard/Ars-Zero/pull/34).
  - Conjures a stationary spherical barrier around a block or entity target.
  - Absorbs melee attacks and projectiles, has durability, and lasts 60 seconds by default.
  - `Amplify` increases durability, `Extend Time` increases duration, and up to three `Split` augments create as many as seven shields.
  - `AOE` makes the barrier reflective at the cost of increased melee damage to the shield.
  - The caster's own outward-moving projectiles can leave the barrier safely.
  - `Sustain` can extend an existing shield's lifetime.
- Added a large full-bright purple Arcane Shield visual with layered shells, animated runic bands, orbital rings, pulsing, damage feedback, hit sounds, and break particles.
- Added the Arcane Shield glyph icon, item model, crafting recipe, Worn Notebook entry, augment descriptions, and English, Simplified Chinese, and Traditional Chinese localization entries.
- Added the **Staff of Aetherwalk**, which conjures an AOE phantom-block path beneath the wielder while channeling.
- Added the uncraftable **Creative Filial** and its animated rainbow renderer; Creative Spell Staves now receive it by default.
- Added Worn Notebook documentation for the Blight Forest and the underground Necropolis.

### Changed

- Moved Blight Forest weight to the common config at `config/ars_zero-common.toml` so it is available when TerraBlender regions are registered.
- Blight Forest weight now controls its actual TerraBlender region weight; `0` disables registration. A full restart is required, and world-generation changes only appear in newly generated chunks.
- TerraBlender is now an explicit required dependency. Blight Forest and Necropolis generation can no longer fail silently because TerraBlender was omitted.
- Added a startup log showing the applied Blight Forest weight or that generation is disabled.
- Unified spell-staff and static-staff rendering, including consistent inventory transforms, tier geometry, dyes, and filial rendering.
- Telekinesis and Aetherwalk now use preset school filials and the standard staff renderer.
- Ice and Fire voxel collisions now extinguish the Fire voxel while preserving the Ice voxel instead of creating a Water voxel.
- Removed outdated example pages from the Worn Notebook.
- Updated NeoForge dependency metadata to current `type="required"` declarations and made the packaged mod version follow the Gradle release version.

### Fixed

- Fixed the Psion's Circlet tick-delay setting resetting after confirmation by updating the exact temporarily held circlet before it returns to its Curios slot ([#93](https://github.com/zeroregard/Ars-Zero/issues/93), [#104](https://github.com/zeroregard/Ars-Zero/issues/104)).
- Fixed multiphase staves failing to enter the Tick phase when the Begin phase is intentionally empty.
- Fixed projectile and other descendant spell resolvers leaving Begin unfinished, which prevented staff and turret Tick phases from starting.
- Fixed Multiphase Spell Turrets becoming inert after a powered chunk or world reload by treating power-edge tracking as runtime state.
- Fixed Multiphase Spell Turrets retaining stale casting context after their End phase.
- Fixed a block duplication exploit involving Temporal Context, Gravity, Snare, Sustain, Beam, Split, and Extend Time:
  - Removed or dead falling-block targets are no longer retained or resolved.
  - The same entity UUID is recorded and resolved only once per temporal context.
- Fixed the Arcane Shield collapsing after roughly half a tick when the base spell reported a zero duration multiplier; it now receives its full default lifetime.
- Fixed Arcane Shield projectiles being incorrectly blocked when fired outward by the shield owner.
- Fixed Arcane Shield reflection and collision behavior for a surrounding spherical barrier.
- Fixed the Arcane Shield appearing as a tiny flat box; its visual and collision volume now surround a player.
- Fixed the Arcane Shield glyph showing a missing or black-and-purple placeholder by adding both its texture and item-model mapping.
- Fixed spell-staff models hiding their central source crystal and corrected rendering for novice, mage, archmage, creative, and static staves ([#97](https://github.com/zeroregard/Ars-Zero/issues/97)).
- Fixed the Telekinesis Staff using a mismatched custom renderer and corrected its Ars Nouveau dungeon-loot lookup.
- Fixed Fire and Water voxel periodic environmental effects running immediately on their spawn tick.
- Fixed Blight Forest config changes being ignored during TerraBlender registration ([#99](https://github.com/zeroregard/Ars-Zero/issues/99), [#107](https://github.com/zeroregard/Ars-Zero/issues/107)).
- Fixed outdated 1.21.1 NeoForge dependency metadata syntax; the final release intentionally declares TerraBlender required.
