Subject: [PATCH] fix: add Windows support for CLI path and command execution

- Use double quotes instead of single quotes around paths (Windows compatibility)
- Replace bash-based base64 pipe with temp file approach to avoid command length limits
- Use shell: true instead of hardcoded /bin/bash for cross-platform support
