Display Librarian Enchant Trades

V4.0 — Major rewrite (Actionbar-based, multiplayer-safe)

New / Changed

• Complete recode of the datapack’s core logic (old systems removed).
• Switched from text displays above villager heads → actionbar above the hotbar, for a cleaner UI and no lingering entities.
• Auto-updates when you look at a different villager, so the shown trades stay in sync with what you’re inspecting.
• “Only show max-level enchants” toggle works reliably again (per-player trigger).

Compatibility / Technical

• Updated to Minecraft 1.21.5 pack format and 1.21.5 text component / NBT changes.
• Uses a periodic “remember + refresh” approach and only recomputes when the villager’s trade count changes, reducing unnecessary entity data reads.

Fixes (addresses all V3 known issues)

• Fixed cycling glitches (including the “last trade is a book trade” edge case).
• Fixed multiplayer desync/favoring one player (tested in multiplayer).
• Fixed persistent/leftover nameplate/text display artifacts (no more stuck displays when villagers die).
• Fixed reset/animation-like flicker that came from rebuilding nameplates every cycle.

Localization

• Added enchantment name translations, including Lunge.
