Resonant Synthesis [Deeper and Darker]

Added

• New Advancement:
  • "Echoes of the Deep" / "Эхо Глубин" - triggers when witnessing Warden's sonic boom convert amethyst into Echo Shard
  • Custom criterion trigger for the advancement event
  • Players within 50 blocks of the conversion receive the advancement
• Custom Criterion Trigger System:
  • EchoShardConversionTrigger - custom trigger for advancement
  • RSCriteriaTriggers - registration class for custom triggers
  • Integration with Forge event system in commonSetup

Changed

• All EPIC and RARE items are now fire resistant (won't burn in lava/fire)
• Deepslate Sculk Ore now requires diamond pickaxe instead of netherite

Fixed

• Echo Shard Conversion Reliability:
  • Sonic boom → Echo Shard conversion now works 100% of the time
  • Previously was intermittent due to LivingAttackEvent only firing when hitting entities
  • Now uses Mixin injection for guaranteed triggering

Technical

• Added MixinSonicBoom - injects into SonicBoom.tick() method for reliable sonic boom detection
• WeakHashMap cooldown system (60 ticks) prevents duplicate triggers per sonic boom cycle
• Updated EchoShardHandler from event-based to direct method invocation
• Added mixin to mixins.resonant_synthesis.json
