Enchanted Tool Expansion v2.1.4 — Quarry locator proof

- Keeps the proven minecraft.mined:minecraft.netherrack completed-break detector.
- Replaces the outdated dropped-item NBT selector in Quarry with:
    execute as <nearby item> if items entity @s contents minecraft:netherrack
- Matching drops are temporarily tagged et_quarry_drop_match.
- Quarry then uses `positioned as` the matching drop, preserving the PLAYER as @s.
- This fixes the executor-context bug that prevented et_quarry_anchor_found and player UID ownership.
- Quarry II remains 2x2.
