v1.13.0

Added

• Agent color frontmatter. Agent .md files can set color: <named-color> or color: #RRGGBB in frontmatter. The agent's status icon is tinted with that color across all UI surfaces, including widget connector lines and a new toggle in General settings.
• Background agent status indicators. When an agent is scheduled to run in the background, the UI now clearly shows its status in the call-line icon: ◆ (accent) when queued, ◈ (accent) when running, ✓ (success) when completed or turn-limited, ✗ (error) on error or abort, and ■ (dim) when stopped; foreground call lines show ▸. The result line shows the model tag and stats for finished foreground agents and the description only for background agents (icon lives in the call line). Live status updates via invalidation map — the icon flips as the agent progresses.
• Model picker prioritizes configured models. The model picker (via /model, model settings, concurrency settings, and spawn wizard) now shows models sorted: current model first, then models from subagents-lite.json agent config (default + per-type overrides), then all remaining models. This makes configured models easy to find without searching. Search/filter still works correctly with the new sort order.

Changed

• Flattened settings menu. Reworked setting menu into 5 top-level categories for easier navigation.
• Unified agent status icons across all UI surfaces. Tool call lines, the subagent status widget, and the conversation viewer now share one status→icon map (statusIcon in format.ts): ◆ queued, ◈ running, ✓ completed (success), ✓ turn-limited (warning), ✗ error/aborted, ■ stopped (dim), ▸ when no status yet.
