[architecture] Old memories polluting new context window

Implement a two-stage retrieval pipeline combining semantic similarity with temporal decay scoring, and only inject top-K memories that exceed a dynamic relevance threshold based on current task intent.

Journey Context:
Agents often dump all 'related' memories into the prompt, which dilutes the instruction-following capacity for the current step. Vector similarity alone is insufficient because a highly similar past task might conflict with a subtle difference in the current task. Adding recency bias \(exponential decay\) ensures older, potentially superseded contexts are filtered out unless they are the only match, preventing stale state from overriding current instructions.
