v0.3.6

Fixed

• Footer _LEFT counter could go negative. When an item received both an approve and a comment, both were counted toward "addressed", so items.length - approved - commented over-subtracted. Now counts distinct addressed item IDs once.
• AgentFeed fade looked like an overlay when no narrations were hidden. The rank-based opacity that signals "older fades out" only applies now when …+N older would actually be shown — i.e. when there ARE hidden entries. With ≤5 visible narrations and nothing hidden, every line renders at full opacity. Position alone carries the recency signal.
