PostPile 0.13.0

Added

• "Move to topic…" in a tile's ⋯ menu opens a searchable picker instead of listing every topic. It suggests topics with the same people and the most recently active ones; finished topics only show when you search.
• Agent-assisted Approve and Mark read on topics and tiles, marked ✨; Approve updates at once and no longer shows Undo.

Changed

• The sidebar's four filter buttons are now one switch: "Topics with any PR | my PRs | team PRs". The sections stay while it narrows, and a line says how many topics it hides, with "Show all". Reply and Review are gone: the Needs reply and To review sections show those.
• A topic that holds your own PR next to other people's work sits where that work puts it (a review waiting on you puts it under To review), not under My PRs.
• Inside a topic, your own tiles come first in each group.
• Topics are sized like projects: one goal over days or weeks, not one PR each. After this upgrade, PostPile tidies your existing topics once: it merges ones that are too small and splits ones that are too broad. PRs you moved by hand stay where you put them, and the tidy doesn't ask you through proposals.
• The MCP server refuses to answer while the PostPile app is closed, with a one-line error asking you to open it. It answers again as soon as the app is back, no reconnect.
• Update reminder: after 24 hours behind, the small title bar pill becomes a bar under the title bar with how many releases you missed, the brew command and release notes. "Later" brings back the pill for a day, then the bar returns.
• Sets (tiles that hold several PRs) now group PRs you can judge in one go: the same change in several places, or one small step of the goal, with similar risk. A set keeps its PRs until the agent changes it for a stated reason; a PR never moves because of its status, a review or a merge, and merged PRs stay in their set.
• Each change to a set is recorded with its reason. The CLI topic command and the MCP topic tool (detail "full") list them.
