fix(git): prevent app freeze on repos with large untracked directories

[CaioDGallo]

Problem

The app freezes (macOS beach ball) when selecting a repository that contains a large untracked directory (e.g. .pnpm-store/ not in .gitignore). The main process becomes unresponsive because multiple git queries run git status which enumerates every file inside untracked directories.

Changes

simple-git's .status() hardcodes a -u flag, which is shorthand for --untracked-files=all. This makes git recursively list every file inside untracked directories, a .pnpm-store/ can contain tens of thousands of files, all piped through stdout and parsed synchronously by simple-git.

From simple-git's source (src/lib/tasks/status.ts)[https://github.com/steveukx/git-js/blob/main/simple-git/src/lib/tasks/status.ts]:

function statusTask(customArgs) {
  const commands = ["status", "--porcelain", "-b", "-u", "--null", ...customArgs];
  // ...
}

Custom args are appended after -u, so passing --untracked-files=normal or --untracked-files=no overrides it (last flag wins in git).

What changed in packages/git/src/queries.ts:

1. All git.status() calls now pass an explicit --untracked-files mode:

   • --untracked-files=normal for functions that read not_added — collapses untracked directories into a single entry instead of listing every file inside them (matches default git status CLI behavior)
   • --untracked-files=no for getAheadBehind and getSyncStatus which only read branch/ahead/behind info and don't need untracked data at all

2. getChangedFilesDetailed: capped countFileLines to the first 10,000 untracked files. This function sequentially reads every untracked file to count lines, which can cause a secondary bottleneck after the status enumeration.

No behavior change: --untracked-files=normal still reports untracked content, just grouped by directory instead of expanded per-file. isClean(), not_added, modified, staged, deleted, ahead, behind all remain correct. Functions using --untracked-files=no never accessed untracked fields to begin with.

How did you test this?

Manually selected a repository containing a large untracked .pnpm-store/ directory via the folder picker. Before the fix, the app froze with a beach ball. After the fix, the repo loads without freezing.
