fix(installers): Enable one-line installation from curl/web

- Add automatic download from GitHub when files not present locally
- Support both local and remote installation modes
- Download v1.0.0 release tarball/zip automatically
- Clean up temporary files after remote installation
- Update both install.sh (macOS/Linux) and install.ps1 (Windows)

Now the one-line install works correctly:
curl -fsSL https://raw.githubusercontent.com/alirezarezvani/ClaudeForge/main/install.sh | bash

Fixes #1 (if issue exists)
