fix: Add X-Tigris-Consistent headers and fix Windows rclone config path

- Add X-Tigris-Consistent: true headers to rclone commands for global strong consistency
- Fixes stale content reads for non-US users hitting Tigris edge cache
- Update get_rclone_config_path() to use runtime detection via rclone config file
- Supports Scoop, Chocolatey, and manual rclone installations on Windows
- Add tests for new headers and runtime config detection

Fixes #548
