v0.4.2

New Features

• Added Agent V1 MCP tools for richer agent-side Rudder operations.
• Added an Appearance settings surface with expanded base color palettes and
  action color themes.
• Added chat message scroll-map navigation for faster review of longer
  conversations.

Improvements

• Improved agent integration setup and bundled skill defaults so runtime answers
  stay scoped to the selected skill and integration actions remain safer by
  default.
• Improved local runtime compatibility for Pi, OpenCode, and Codex follow-up
  flows.
• Improved Desktop release verification around packaged server dependencies and
  bundled PostgreSQL runtime payloads.

Bug Fixes

• Fixed packaged Desktop startup by ensuring the PostgreSQL 18.4 runtime payload
  is bundled into the app resources used by prod_local.
• Fixed chat composer recovery after stopped replies and tightened chat
  navigation edge cases.
• Fixed repeated Feishu stop-command handling and other integration setup
  details.
