Enchanted Tool Expansion v2.1.9 — Minecraft Java 26.2

REGRESSION ROLLBACK
- Rebased on v2.1.6, the last build whose normal Quarry II activation was proven in-game.
- Removed the unproven v2.1.7 rapid-mining queue logic entirely.
- Retained the proven 26.2 modern enchantment matching and item-locator chain.
- Retained the v2.1.6 Excavator and Harvester trigger rollout.

DETERMINISTIC AREA RULES
- Level II: selected/broken block is the lower-left block in the player's view.
- Level III: selected/broken block is the center block.
- Applied to Quarry, Excavator, Harvester harvesting, and Harvester tilling.

Rapid-mining loss is intentionally NOT addressed in this build.
First restore/prove normal activation, then solve rapid mining without altering the proven trigger chain.
