chore: Add environment configuration template and clean up utility scripts

- Add .env.example with comprehensive configuration documentation for database, authentication, storage, and node settings
- Update .gitignore to explicitly track .env.example while excluding all .env variants
- Add IDE configuration directories (.vscode/, .kiro/) to .gitignore
- Remove clear_bots.ts and inspect_bots.ts utility scripts that are no longer needed
- Improve environment setup experience for new developers by providing a clear template with all required and optional configuration options
