feat: Add version selection support to installation scripts

Enhanced both Windows and Linux/macOS installation scripts with flexible version selection:

New Features:
- Version selection: stable (default), latest, or branch
- Specific release tag installation (e.g., v3.2.0)
- Auto-detection of latest stable release via GitHub API
- Clear version information displayed during installation

Installation Script Updates:
- install-remote.ps1: Added -Version, -Tag parameters
- install-remote.sh: Added --version, --tag flags
- Updated help documentation with examples
- Improved user prompts with version information

Documentation Updates:
- README.md: Added installation examples for all version types
- README_CN.md: Added Chinese installation examples
- Clear distinction between stable, latest, and specific versions

Examples:
- Stable (recommended): Default one-liner installation
- Latest: --version latest flag
- Specific: --version stable --tag v3.2.0
