v0.3.1

v0.3.1

Added

• Agent modes: Agent / Chat / Plan three conversation modes with mode selector and per-user default setting.
• Plan mode: read-only planning with canvas preview; confirmed plans hand off to Agent mode via one-click Build.
• Chat description: auto-generated subtitle for each conversation.

Changed

• Renamed orchestrator tools for clarity (create_plan, define_step, validate_draft, create_workflow, update_workflow, load_workflow).
• validate_draft now enforces graph validation and inputSpec completeness.
• Removed deprecated models (xAI Grok 4.1, Qwen 3.5 Plus, DeepSeek R1).

Migration

• Run prisma migrate deploy; adds agentMode and description columns to Chat and migrates legacy tool names in message data.
