Git root detection rejects bare repositories and .git folder layouts

What

Claude Code checks whether the folder it runs in is the top of a git project, meaning a folder tracked by the git version-control tool. Before, any folder with a .git file or folder counted as the root. Now there is an extra check.

• A folder with a .git entry is classed as "other" rather than "root" when the check finds a bare repository (a git store with no working files) or a gitdir: file layout along the path.
• A folder with no .git is classed as "other" rather than "absent" when a bare repository is found above it.
• The not_git_checkout explanation now says the run may be inside a bare repository or a .git folder. Before, it said the .git was missing, could not be opened, or was not a plain file or folder.

Why

This can change which folder Claude Code treats as your project root. If you work inside a bare repository or a .git folder, Claude Code now refuses to treat it as a normal checkout and tells you why.
