Better Gold Expansion

Better Gold 1.7.0

Two new metal lines - Chaos Gold and Imbalance Alloy - plus the Money Gremlin, the Sturdygold Anvil, High-Precision Alchemical Oil and the Golden Prison nether structure.

• Chaos Gold: 11 building blocks, 14-piece gear, randomised damage / mining speed / damage reduction that re-rolls on switch, hit, mine and being hit. Its coins can substitute into Copper / Iron / Gold Block and Netherite Ingot recipes.
• Imbalance Alloy: the tier above it - higher caps, 50% chance on any hit to apply Strength or Resistance Imbalance; its shield, armor and forbidden fruit do the same.
• Money Gremlin: floating nether mob, coin-string melee and an eight-way barrage; its coins stack hunger up to 12. Weak to fire, lava and Flamegold.
• Sturdygold Anvil: a full anvil with no repair penalty, repairs with Chaos Coin Strings for 1 level.
• High-Precision Alchemical Oil: brewed from Golden Torchflowers, doubles precious-metal raw material output.
• Golden Prison: 26-template nether dungeon, one treasure room per structure, at least three four-way junctions, never in Basalt Deltas.
• Handbook: new "Golden Prison" category (6 chapters) and "Advanced Precious-Metal Extraction"; the Chaos Gold chapter gained a two-recipe page. Now 5 categories / 27 entries / 231 pages.
• 63 advancements and the Money Gremlin's own sounds with subtitles.
• Fixes: handbook no longer shows "Format error", our buffs survive milk, Echo Roar no longer hits its caster, the Golden Prison's air / entities / chest loot are exported, Thornsgold armor no longer wears down on sweet berry bushes.

Farmer's Delight and Patchouli stay optional; existing worlds are unaffected.
