v0.2.8

• Added built-in Herdr integration that reports agent lifecycle state to Herdr panes automatically, without requiring herdr integration install pi.
• Changed Escape to interrupt active work with a visible abort notice, double Escape to open the session tree from an empty prompt or clear an idle draft, and ? to show shortcuts (ENG-4489).
• Changed new-chat guidance to show concise shell, command, file, and shortcut hints, with Agents View first and ? for shortcuts after the model and effort (ENG-4489).
• Changed ? shortcut help to appear as a temporary compact panel below the transcript, while /hotkeys shows the full reference without Ctrl+Z (ENG-4489).
• Fixed Escape repeats around autocomplete, queued draft restoration, whitespace-only drafts, and active background work (ENG-4489).
• Fixed the agents-view splash shifting when opening an agent session (ENG-4517).
• Changed /model to sort featured flagship models above a provider's long tail (with a numeric-aware alphabetical tiebreak), so the full Prime Inference catalog doesn't flood the picker.
• Fixed selector prompts and choices filling their background through the terminal's right edge.
• Changed automatic harness refinement to be enabled by default while keeping autoRefine.enabled: false as the opt-out.
• Fixed non-numeric autoRefine.turnInterval and autoRefine.cooldownMs settings falling back to defaults instead of silently enabling a noisy auto-refine loop.
• Fixed all session-resume entry points to share a searchable full-screen picker, stream results while loading, and support renaming (ENG-4513).
