refactor: restructure client modules and add config file supportv0.8.1

- Split large osint.go client into focused modules (bssid.go, breachforum.go, buckets.go, etc.)
- Add config file support with init command for API key management
- Remove api-key flag in favor of config file + env var fallback
- Update API paths to remove /osint prefix
- Add crawl endpoint streaming support
- Improve error handling with 402 payment required status
