feat: auto-detect CLI version from git tags

- Replace hardcoded version with dynamic detection from git tags
- Try Composer\InstalledVersions first, then git describe, then fallback
- Extract version number from git describe (e.g., v2.10.2-12-gabc123 -> 2.10.2)
- Show exact tag version when on tagged commit, latest tag version otherwise
- Remove -dev suffix as version should match current project version
