refactor: Remove serializer and polymorphed forms from AttributableObject AC in favor of generic helper function

1. Decoupled Attributes Serialization:
      • Removed all  serialize()  methods from  AttributableObject
(attribute.ts),  WorldState  (world.ts), and  Entity  (entity.ts).
      • Implemented a standalone, uncoupled function
serializeAttributes(attributes: Attribute[]): string  in attribute.ts.
This function receives an array of attributes and outputs their
formatted
      representation.
  2. System Objective Serializer:
      • Implemented  serializeObjectiveWorldState(worldState:
WorldState): string  in world.ts for system LLMs that need objective
reality dumps (e.g. validators and intent decoders). It manually
      retrieves and formats attributes using  serializeAttributes()
alongside class-specific fields like  locationId .
  3. System prompt updates:
      • Updated  LLMValidator  (llm-validator.ts),  TimeDeltaGenerator
(delta.ts), and  IntentDecoder  (intent-decoder.ts) to use the new
standalone  serializeObjectiveWorldState(worldState)  helper imported
      from  @omnia/core .
  4. Unit Tests (Tier 1):
      • Updated core.test.ts to verify  serializeAttributes  and
serializeObjectiveWorldState  utilities directly.
