Recognize git worktree roots in @netlify/config

[Hashim1999164]

Summary

Git worktrees store a .git file rather than a directory. getRepositoryRoot only looked for a directory so worktree checkouts fell back to cwd and broke path resolution.

This also looks for a .git file so worktree roots resolve correctly.

Fixes netlify/cli#7868

Test plan

• Added unit test covering a .git file worktree layout
• Ran packages/config cwd tests

📝 Summary

Summary by CodeRabbit

• Bug Fixes

  • Improved repository detection for Git worktrees by recognizing .git files as well as .git directories.
  • Correctly resolves nested paths to their worktree repository root instead of falling back to the current directory.
  • Ensures the nearest Git marker is used when worktrees are nested within another repository.

• Tests

  • Added regression coverage for repository root detection in Git worktrees, including nested worktree scenarios.

Walkthrough

getRepositoryRoot now performs one upward search for the nearest .git file or directory. Regression tests cover worktree .git files and the case where a nearer worktree marker must take precedence over a parent .git directory.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to e53bb

Repository-root detection now recognizes the nearest .git marker, including worktree files, so CLI path and configuration resolution works from nested worktrees. No current merge-blocking risk remains.

Updated getRepositoryRoot to walk once and take the nearest .git marker, file or directory. A parent .git directory no longer hides a closer worktree .git file. Added a nested worktree regression test for that case.
