Fixed issues	#211, #333

symplify/git-wrapper is abandoned and depends on nette/utils v3.2.10 which requires PHP <8.4, breaking compatibility.

Changes

• composer.json:
  • Replace symplify/git-wrapper with gitonomy/gitlib ^1.5
  • Update PHP requirement from ^8.0 to ^8.1 (required by symfony/process ^6.0 and gitonomy/gitlib ^1.5)
• New adapter layer (src/Infrastructure/Git/):
  • GitRepository - wraps Gitonomy\Git\Repository with compatible API
  • GitBranches, GitTags - simple value containers
  • GitException - exception wrapper
• Updated consumers: Package.php, AddChangelogCommand, PushCommand, MakeCommand, ContributorsCommand

The adapter maintains API compatibility - callers use the same method names (getBranches(), tags(), checkout(), push(), etc.).

// Before
$git = $package->getGitWorkingCopy(); // Returns Symplify\GitWrapper\GitWorkingCopy

// After  
$git = $package->getGitWorkingCopy(); // Returns Yiisoft\YiiDevTool\Infrastructure\Git\GitRepository
$git->getBranches()->all();           // Same API
$git->tags()->all();                  // Same API

Breaking Change

The minimum PHP version requirement has been increased from ^8.0 to ^8.1. This is required because the Symfony 6.x packages and gitonomy/gitlib ^1.5 require PHP 8.1+.

<issue_title>Repo not compatible with PHP 8.4</issue_title> <issue_description>I am using this repo to run some basic tests for Yii 3.0 Docker images, but it is not compatible with PHP 8.4

https://github.com/yiisoft/yii-docker/actions/runs/18778578433/job/53578822639

 Root composer.json requires symplify/git-wrapper ^10.2.0 -> satisfiable by symplify/git-wrapper[10.2.0, ..., 10.2.7].
    - nette/utils v3.2.10 requires php >=7.2 <8.4 -> your php version (8.4.13) does not satisfy that requirement.

There's no newer version of symplify/git-wrapper, it is also marked as abandoned, see https://packagist.org/packages/symplify/git-wrapper</issue_description>
