feat: Enhance OAuth module and OpenRouter client functionality

- Updated OAuth module to include unused imports for better clarity.
- Refactored OpenRouterClient to improve chat functionality and added support for tools in chat requests.
- Modified internet tools (Download, Fetch, Search) to use a more flexible internet mode check.
- Introduced new Bash tools for managing background jobs (BashOutput, BashKill).
- Enhanced workflow tool to parse and execute workflow scripts with arguments.
- Updated status and workflow views to reflect new agent and findings counts.
- Added IPC protocol definitions for client requests and state payloads.
