[architecture] Agent memory grows infinitely leading to degraded retrieval performance and high storage costs

Implement memory consolidation: periodically summarize or merge related episodic memories into higher-level semantic memories, and delete the raw episodic nodes once consolidated.

Journey Context:
Storing every single step or observation creates a massive, noisy memory stream. Just like human sleep cycles consolidate daily events into long-term lessons, agents need a background process to compress 'I did X, then Y, then Z' into 'To achieve W, do X->Y->Z'. This keeps the vector store dense with high-signal insights rather than low-signal logs, improving both retrieval speed and accuracy.
