[Feature Request]: Allow Agent Init/Import in the JVCLI Client

[ChrisIsKing]

Is your feature request related to a problem? Please describe.
Currently, in jvcli, there is no easy way for users to re-import an agent directly from the jvclient UI. If users make changes to an agent, they have to manually call the API to trigger an agent re-import using init or import agent, which is inconvenient and slows down development.

Describe the solution you'd like

• Add a "Re-import Agent" button in jvclient that allows users to reload an agent with the latest changes on the fly.
• Clicking the button should trigger a backend request to reload the agent without requiring users to interact with the API directly.
• The process should:
  1. Identify the selected agent.
  2. Call the appropriate API endpoint to re-import and reinitialize the agent.
  3. Display feedback to the user indicating whether the re-import was successful.

Implementation Plan

1. Modify jvclient UI

   • Add a "Re-import Agent" button next to the agent selection panel.
   • Ensure the button is only enabled when an agent is selected.

2. Implement API Trigger

   • On button click, send a request to the appropriate endpoint in jvserve to reload the agent.
   • Ensure the request includes the correct agent ID.

3. Provide User Feedback

   • Display a success message if the agent reloads successfully.
   • Show an error message if the reload fails, with debugging information.

Expected Benefits

• Improves developer workflow – Allows users to apply changes instantly without needing to restart services or manually call the API.
• Enhances usability – Provides a more intuitive way to update agents directly from the UI.
• Reduces friction – Removes the need for extra steps, making agent management smoother and more efficient.

Describe alternatives you've considered

• Keeping the manual API trigger workflow, but this adds unnecessary complexity for users.
• Implementing an automatic reload on file change, but this could introduce unintended side effects.

Additional context

• This feature aligns with existing agent management functionalities in jvclient and enhances the real-time usability of jvcli.
• Future enhancements could include auto-reload on file save or batch updates for multiple agents.
