Feature/major module updates and fixes

[HelixCraft]

major module updates and fixes
(the HoleTunnelStairsESP Improvements took so fucking long)

• Auto Shop Order (AutoShopOrder.java)

  • Consolidation: Replaces legacy modules AutoBlazeRodOrder, AutoShulkerOrder, AutoTotemOrder, AutoShulkerShellOrder, and AutoShellOrder.
  • Logic: Features a robust state machine for navigating /shop, bulk buying, and identifying the most profitable /orders.
  • Features: "AUTO" pricing (Shop + $1), custom price suffixes (K, M, B), player blacklist, and an anti-stuck system.

• Pearl Landing Predictor (PearlLandingPredictor.java)

  • Function: Simulates Ender Pearl trajectories to predict and highlight landing points. (for other player)
  • Features: Player filtering, live updates for new chunks, and distinct rendering for unknown owners.

• AH Sell Command (.sell_hotbar)

  • Function: Command-based version of AHSell.java. Automatically lists all hotbar items via /ah sell .

• AH Item Command (.ahitem)

  • Function: Instantly searches the Auction House for the item in hand.
  • Smart Search: Automatically appends enchantments (e.g., sharpness 5) and "stack" parameters to the search query.

Module Improvements and Refactors

HoleTunnelStairsESP (Major Overhaul) - this shit took so fucking long

The CoveredHole.java module has been fully integrated into HoleTunnelStairsESP to centralize logic and reduce overhead.

• Variable Tunnel Width: New minTunnelWidth / maxTunnelWidth settings (default 1–3) for detecting 1x1 to 3x3 tunnels.
• Covered Hole Detection:
  • Identifies 1x1 and 1x3 holes covered by solid blocks.
  • Smart Filtering: only-player-covered logic distinguishes player-made covers from natural terrain generation.
  • Dedicated Rendering: Custom colors for covered holes to avoid visual confusion.
• Dynamic Updates: Added undergroundUpdateThreshold and packet listeners for Y < 0 updates on servers with dynamic chunk loading.
• Optimization: Hash-based deduplication (tunnelHashes) for O(1) lookups, preventing redundant rendering across chunk borders.

Bug Fixes

• HoleTunnelStairsESP:

  • Double Rendering: Fixed via canonical start positions and hash-based deduplication.
  • Inconsistent Cross-sections: Fixed ceiling height detection using the refHeight parameter.
  • 1x3 Covered Holes: Corrected detection logic to verify all three top blocks instead of just the start block.

• Pearl Landing Predictor:

  • Fixed a bug where the landing box was not rendering (previously only the name label was visible).

Performance Improvements - pain

• Scan Efficiency: HoleTunnelStairsESP now uses a 2-pass instead of a 3-pass scan, combining length measurement and end-position recording.
• Redundancy Check: Implementation of CANONICAL_TUNNEL_DIRS (East/South only) to prevent scanning the same tunnel from opposite directions.
• Thread Safety: Integrated ThreadLocal BitSet for chunk processing, removing synchronization bottlenecks.
• Caching: Added solidBlockCache and blockStateCache to minimize expensive world-access calls.

Note: Only tested on Minecraft 1.21.4. Compatibility with other versions not verified.
