Prosperity - Loot Overhaul

Party loot lands this release — teammates can share a single instance per container instead of each rolling their own — and a new Prospector's Compass points you straight to the loot you haven't collected yet. The exploration reward loop widens too, now reaching fishing, trial chambers, and clearing a structure to the last chest.

Added

• Party Loot — an optional co-op mode (off by default): players on the same team share one loot instance per container, and the first teammate to open a chest rolls the loot the whole team draws from. It follows vanilla scoreboard teams by default, or your Open Parties and Claims or FTB Teams party when either is installed.
• Prospector's Compass — a gold-cased compass whose needle points at the nearest container you haven't looted yet, and spins when nothing remains nearby. Craft one from a compass, gold, netherite, and an end rod, or find one as rare chest loot from the Frontier tier outward.
• Milestone advancements — a Prosperity advancement tab turns exploration into goals: reach each distance tier, loot 10 / 50 / 250 containers over a lifetime, and cover 3 / 8 / 15 distinct structure types.
• /prosperity stats — check your lifetime loot: total containers looted, a per-tier breakdown, the distinct structure types you've cleared, and the bonus rewards you've received.
• Wider distance scaling — fishing now rolls the catch at the bobber's tier and biases toward treasure the farther out you cast, and trial-chamber vault and spawner rewards scale with the chamber's tier.
• Full-structure bonus — loot every instanced container in a structure and the final one pays an extra tier-appropriate reward, with an action-bar fanfare.
• Peek panel upgrades — hold the peek key for the detail panel and it now lists the unlooted containers around you with distance and bearing, calling out the nearest when you're carrying a Prospector's Compass. The peek key is now bound to Left Alt by default (your existing binding is kept if you set one).
• First-open message — the first time you open instanced loot, a one-time note makes it clear the loot was rolled just for you.
• Meridian integration — with Meridian installed, injected enchanted-book rewards roll live, distance-scaled Meridian enchantments instead of fixed ones.
• Tribulation integration — with Tribulation installed, local danger adds bonus luck to your loot, and dangerous mobs drop their tier gear more often the farther out they roam.

Changed

• Bonus loot from distance-tier chests is rebalanced: it's no longer guaranteed on every eligible container and no longer defaults to a level-3 Sharpness or Protection book. Each container now has a tuned chance at a wider, rarity-banded reward pool.

Fixed

• The unlooted sparkle on a double chest now sits over the seam of the pair and twinkles correctly in modpacks whose texture mods honor animation metadata, where it could previously render as a mistimed rod.
• The tier badge and peek panel no longer flicker or vanish under ImmediatelyFast or Blur+.
