Summary by cubic

Adds a chat agent settings UI so users can enable/disable agents and set a default agent directly from the chat settings panel. Introduces a modal-driven flow that updates the app state and keeps the default selection in sync.

• New Features

  • Agent list with availability toggles and a per-agent settings modal.
  • “Set as default” updates enabledAgents, ensuring only one default and the agent remains enabled.
  • Disables the default action when an agent is unavailable or already default.

• Refactors

  • Extracted AgentList and AgentSettingsModal components; simplified ChatSettingsPanel.
  • EnabledAgent now includes a default flag; index.svelte ensures the chat app loads before updating and centralizes default switching logic.

^{Written for commit 3af77d0. Summary will update on new commits.}
