New Features:

• Memory Decay: Per-project search-time ranking bias that boosts recently-used memories and gently dampens stale ones. Opt-in via decay on the project endpoint; off by default. The scaling factor stays in 0.3×–1.5×, the public score remains clamped to [0, 1], and the bias never filters a candidate out. See Memory Decay docs.
