IG: Ore Amplifier (Vein count)

Added

• 5-Pillar Testing & Runtime Verification Harness ([BL-OA-003]): Implemented comprehensive testing suite satisfying studio verification standards:
  • Pillar 1 (OreAmplifierStressFuzzTest): 20,000 deterministic chaos property fuzzing iterations verifying getAmplifiedCount bounds, non-negative saturation, and static blacklist heuristics.
  • Pillar 2 (OreAmplifierConcurrencyLoadTest): 50 virtual worker threads executing 20,000 operations verifying deadlock-free concurrency, lock-free config safety, and zero ConcurrentModificationException.
  • Pillar 3 (OreAmplifierCommandTest): Headless Brigadier AST hierarchy assertions, Gamemaster level 2 permission gating, static GameRule handles, and conventional tag keys.
  • Pillar 4 (OreAmplifierGameTest): Headless state simulation validating BuiltInRegistries.BLOCK ore identification, Monte Carlo stochastic multiplier convergence, and sparse delta config pruning.
  • Pillar 5 (OreAmplifierSidednessContractTest): Sidedness isolation asserting 0 client package references in common code/bytecode and verifying single-line GPLv3 license headers across all source files.

Fixed

• Saturated Arithmetic Guard: Enforced integer saturation in OreLogic.getAmplifiedCount, preventing 32-bit signed integer wrap-around on extreme count/multiplier inputs adhering to the Freedom Over Anti-Crash policy.
• Config Concurrency Thread-Safety: Converted OreAmplifierConfig.perOreMultipliers to thread-safe ConcurrentHashMap with synchronized mutation/pruning guards.
