What's New

Multi-OS Support (Linux, macOS, Windows)

This release adds full cross-platform support for all major operating systems.

Changes

New cross-platform file permissions utility (src/utils/file-permissions.ts)
- Uses chmod on Unix systems (Linux/macOS) for standard permissions
- Uses icacls on Windows for ACL-based file restrictions
- Provides secure helper functions: mkdirSecure(), writeFileSecure(), appendFileSecure()
- Exports platform detection flags: isWindows, isMacOS, isLinux
Fixed postbuild script - Now skips chmod on Windows where it's not available
Updated security modules to use the new cross-platform utility:
- crypto.ts - PQ key storage and encrypted file operations
- mcp-auth.ts - Authentication token hash storage
- audit-logger.ts - Audit log directory and file creation

Platform Support

| Linux | Unix chmod (0o600, 0o700) | ✅ Full support |
| macOS | Unix chmod (0o600, 0o700) | ✅ Full support |
