Refactor verdict handling and editor state management

- Removed the Escalate variant from the Verdict enum and associated parsing logic.
- Cleaned up the EditorState struct by removing unused fields and methods.
- Simplified MCP connection functions by removing unnecessary disconnect and handle dismiss functions.
- Added tick count to MiscState for managing UI updates during processing.
- Updated chat and status views to display a spinner during AI processing using the tick count.
- Created a README.md file to document the project, its features, architecture, usage, key bindings, agent modes, security measures, installation instructions, and configuration details.
