feat: add anonymous telemetry system with Supabase integration

- Implement telemetry manager for tracking tool usage and workflows
- Add workflow sanitizer to remove sensitive data before storage
- Create config manager with opt-in/opt-out mechanism
- Integrate telemetry tracking into MCP server and workflow handlers
- Add CLI commands for telemetry control (enable/disable/status)
- Show first-run notice with clear privacy information
- Add comprehensive unit tests for sanitization and config
- Track tool usage metrics, workflow patterns, and errors
- Ensure complete anonymity with deterministic user IDs
- Never collect URLs, API keys, or sensitive information
