Add advancements, class generator, and recipe handling.

- Removed deprecated `Remarkable` annotation/processor.
- Added advancements for Nether and Skyblock progression.
- Introduced `ClassBuilder` for dynamic class generation.
- Implemented `SmeltingCraftingHandler` for custom recipes.
- Updated dependencies for Paper API integration.

+Tasks (actionable steps) Day 1 setup and safety
+- [ ] Preserve starting flora: harvest grass/flowers to secure at least one seed; leave a few grass blocks for spread.
+- [ ] Reposition dirt: place dirt around the starter tree to catch saplings.
+- [ ] Basic tools and bench: craft a crafting table and wooden pickaxe, then move to stone tools.
+- [ ] Cobblestone generator: build a safe, non-flammable design and begin mining.
+- [ ] Shelter and spawn-proofing: build a small shelter and light the area to reduce hostile spawns and phantoms.
+- [ ] Inventory audit: check the starter chest (crops, obsidian, lava, ice, turtle eggs if present) and plan usage.
+
+Early farming and resources
+- [ ] Tree loop: replant saplings promptly; expand the platform to improve drop capture.
+- [ ] Crop start: plant starting crops (wheat/melon/pumpkin/sugar cane) near water.
+- [ ] Melon prep: craft melon seeds if you have a melon slice; plant and manage stems.
+- [ ] Early food: collect apples from oak; supplement with fish once you have string.
+
+Mob farming and animal access
+- [ ] Hostile mob farm (low-tech): build a waterless/pathfinding drop-shaft farm to obtain bones, string, rotten flesh, and occasional iron/redstone from mobs.
+- [ ] Fishing unlock: use string from spiders to craft a fishing rod; fish in your generator’s water channel or a small pool.
+- [ ] Passive mob platform: bridge well away from your island, place grass, and create pens to capture spawned animals.
+
+Crop progression and bone meal
+- [ ] Bone meal loop: convert skeleton bones to bone meal to accelerate crops and tree growth.
+- [ ] Crop diversity: add potato and carrot farming from mob drops; use carrots to lure/breed pigs.
+- [ ] Sugar cane line: expand near water for paper/trade potential.
+
+Water acquisition and duplication
+- [ ] Ice to water: break ice to create flowing water.
+- [ ] Infinite source: create a 2×2 infinite water pool using two sources (or two ice blocks).
+- [ ] Rain capture: place a cauldron under open sky to gather water slowly; bucket it into an infinite source once you have two buckets’ worth.
+- [ ] Underwater bonemeal trick: use bone meal in water to create seagrass and generate source blocks (where mechanics allow).
+
+Villager acquisition and utility
+- [ ] Secure a zombie villager: isolate one from your hostile farm or a night spawn.
+- [ ] Weakness application (no brewing path): bait a witch to throw Weakness at the zombie villager by staying close and with low health.
+- [ ] Weakness application (brewing path): obtain a brewing stand (blackstone/cobblestone), then brew a splash potion of Weakness.
+- [ ] Golden apple prep: acquire gold (Nether piglins, smelt mob-dropped armor, or drowned—version dependent) and craft a golden apple.
+- [ ] Cure and protect: cure the zombie villager and secure it; then build a basic villager breeder.
+- [ ] Trading starter: set up initial workstations (e.g., farmer/librarian/cleric) for emeralds, gear, and books.
+
+Iron farming
+- [ ] Minimal iron farm: assemble 3 villagers, 3 beds, and a non-despawning zombie (holding an item); build a safe kill chamber.
+- [ ] Scale-out: duplicate the farm or upgrade design to increase iron per hour as needs grow.
+
+Nether progression and farms
+- [ ] Portal access: light a Nether portal (using provided obsidian or lava/water methods as appropriate).
+- [ ] Biome-targeted farms:
+    - Nether Wastes: gold from zombified piglins (simple roofed spawning pad).
+    - Crimson Forest: hoglin farm for pork.
+    - Warped Forest: enderman farm for pearls.
+    - Basalt Deltas: magma cube farm for magma cream.
+    - Soul Sand Valley: ghast farm for tears and additional gunpowder.
+
+- [ ] Piglin bartering post: trade gold for utility items (blackstone, crying obsidian, gravel, quartz, soul sand).
+- [ ] Fortress utilization: locate a Nether fortress in the void; collect blaze rods, bones, coal, soul sand, and wither skulls.
+
+Wither and late utility
+- [ ] Wither prep and fight: obtain three skulls and soul sand; defeat the Wither safely; craft a beacon.
+
+Goals (milestones) Foundational milestones
+- [ ] Establish a reliable cobblestone generator and upgrade to full stone tools.
+- [ ] Secure renewable food sources (crops and/or fishing).
+- [ ] Build a functioning hostile mob farm yielding bones and string consistently.
+- [ ] Create an infinite water source using any valid method available to your map/version.
+- [ ] Acquire your first animals via a passive mob platform.
+
+Villager and economy milestones
+- [ ] Cure your first zombie villager and protect them.
+- [ ] Build a villager breeder and produce multiple villagers.
+- [ ] Open a trading loop that generates emeralds steadily.
+- [ ] Obtain enchanted gear (tools/armor/books) through villager trades.
+
+Metal and automation milestones
+- [ ] Construct your first iron farm and achieve steady iron income.
+- [ ] Scale your iron production to meet tool/automation demands.
+
+Nether milestones
+- [ ] Activate and safely use a Nether portal.
+- [ ] Build a basic gold farm and unlock piglin bartering.
+- [ ] Acquire key bartering outputs (blackstone, gravel, quartz, crying obsidian, soul sand).
+- [ ] Locate and utilize a Nether fortress for blaze rods and skulls.
+
+Combat and power milestones
+- [ ] Craft a brewing stand and brew splash Weakness potions.
+- [ ] Defeat the Wither and place your first beacon.
+
+Challenges (optional constraints or variants) Resource and progression constraints
+- [ ] Waterless start: reach infinite water using only rain-in-cauldron collection.
+- [ ] No-redstone early: construct a fully passive/pathfinding-based hostile mob farm.
+- [ ] No-bone-meal: grow crops and trees without bone meal until Nether access.
+- [ ] No-fishing: establish sustainable food without fishing.
+- [ ] No-villager-trading until iron: reach an operational iron farm before any trades.
+
+Villager-specific constraints
+- [ ] Witch-only cure: cure your first villager via a witch’s Weakness potion (no brewing).
+- [ ] No-Nether cure: obtain a golden apple and cure a villager without entering the Nether (relying on armor smelts/drowned for gold; version dependent).
+
+Mob farm and safety constraints
+- [ ] Spiderless farm: design a hostile farm that prevents spider spawns while keeping rates high.
+- [ ] Phantom-proof base: eliminate phantom risk via shelter design and lighting without relying on frequent sleep.
+- [ ] Zero fall deaths: complete early bridging/expansion without falling into the void.
+
+Nether farming variants
+- [ ] Biome mastery: build one working farm in each Nether biome (piglin, hoglin, enderman, magma cube, ghast).
+- [ ] Minimal gold farm: produce bartering-grade gold using a simple low-material pad (no turtle eggs or complex baiting).
+
+Iron farm constraints
+- [ ] Lava-free iron farm: use fall damage or other non-lava methods for the kill chamber.
+- [ ] Minimal villagers: keep iron farm to the smallest villager count while maintaining uptime.
+
+Version-aware constraints
+- [ ] Copper-era start: if drowned drop copper (not gold), reach your first golden apple via alternative gold paths.
+- [ ] Ice-free start: obtain infinite water without ice blocks present.
+
+Collection and completionist variants
+- [ ] Barter unlock list: obtain each notable bartering item at least once.
+- [ ] Fortress-only advance: obtain blaze rods and wither skulls before building non-Nether automated farms.
+- [ ] Farm trifecta: operate simultaneous farms for bones, string, and gunpowder using low-tech designs.
+
+Use these as a menu: pick Tasks to guide immediate actions, track progress with Goals, and spice up playthroughs using Challenges tailored to your map/version.
