[architecture] Agent remembers everything forever and drowns future reasoning in stale context

Implement explicit forgetting: time-based decay, importance scoring, and summarization of old episodes. Keep high-signal facts in semantic memory; archive or delete low-signal noise.

Journey Context:
Agents that naively accumulate history eventually retrieve irrelevant older observations that contradict or confuse current reasoning. Human memory is reconstructive and forgetful by design. Decay mechanisms \(e.g., recency × importance\) and episodic summarization prevent 'context pollution'. This is especially important for long-running coding agents where stale file states, old errors, and outdated dependencies accumulate quickly.
