Support URL Input for Configuration Files #18
Description
Problem
Configuration files must currently be local files. In automation scenarios, configs are often stored in remote locations.
Proposed Solution
Support HTTP/HTTPS URLs for configuration input.
Security Considerations
- Timeout for HTTP requests (default: 30s)
- SSL verification with opt-out flag
- Size limit to prevent memory issues
Acceptance Criteria
- HTTP/HTTPS URLs work for both config options
- Timeout handling
- Clear error messages for network failures
- Documentation updated
