Support "native" Git

### Description

Native git should be supported because:

* JGit inevitably lags behind native git, e.g. support for "gitattributes" [1] took over 7(!) years, and there's still no support for "git worktree" [2] and "includeIf" [3][4]
* JGit's lack of support for certain features leads to unreliable/surprising behavior and possible data loss, e.g. [5]
* NetBeans lags behind JGit, because it needs to upgrade the bundled JGit (currently it bundles 5.7.0, while JGit is at 6.2.0)

No

### Code of Conduct

Yes

Start by reviewing NetBeans' existing Git integration and its bundled JGit dependency, then compare the requested native Git features with the current support. The issue provides no file, test, or entry point, so the implementation boundary and completion criteria need to be established before coding.
