Release v2.1.1: Fix EPERM cross-platform error (#183)

* fix: resolve cross-platform EPERM permissions errors

modManager.js:
- Switch from hardcoded 'junction' to dynamic symlink type based on OS (fixing Linux EPERM).
- Add retry logic for directory removal to handle file locking race conditions.
- Improve broken symlink detection during profile sync.

gameManager.js:
- Implement retry loop (3 attempts) for game directory removal in updateGameFiles to prevent EBUSY/EPERM errors on Windows.

paths.js:
- Prevent fs.mkdirSync failure in getModsPath by pre-checking for broken symbolic links.

* fix: missing pacman builds

* prepare release for 2.1.1

minor fix for EPERM error permission

* Update README.md Windows Prequisites for ARM64 builds

* fix: remove broken symlink after detected

* fix: add pathexists for paths.js to check symlink

* fix: isbrokenlink should be true to remove the symlink
