v0.68.0: Task Management & Harness APIs

Highlights

• Multi-select task deletion — Select and delete multiple tasks at once with deep cleanup of worktrees, sessions, and resources.
• Pinned tasks — Pin important tasks to the top of your sidebar so they're always within reach.
• Inline title editing — Rename tasks directly from the sidebar or navbar without opening a modal.
• Improved MCP connectors — Connectors display in a popover instead of inline chips, and the toggle now works on first click.
• Focused reviews — Reviews now only surface blocking findings, with new dimensions covering security, style, test quality, simplicity, and robustness.

Other improvements

• Added notes textarea to the review picker modal for additional context.
• Fixed inline comments in the Changes tray being lost when git state reloads.
• Input bar action buttons no longer shrink; secondary actions are icon-only.
• Title generation uses thread serializer context with middle truncation, aiming for shorter 3-word titles.
• Enforced compact output format across all prompt modes.
• HyperPlan UI now shows a reconciliation label legend.
• Harness library: new session management API, method-based structuredQuery, and userPromptHandler for interactive input.
• Harness now keeps prompt text out of process argv for improved security.
