### Bug Description When a branch exists in a `git worktree`, rather than a `.git` directory it will have a file called `.git`. This file contains text like so: `gitdir: /home/mrc/dev/main/foocraft/.git/worktrees/name-of-this-branch`. So when the project directory is mounted inside the managed environment, this file (a "fake symlink") no longer points to a valid path, making any tools which need to operate on this as a git repo fail - in this case, `setuptools_scm`. Mounting happens in `craft_application/services/provider.py:123`. Possible solutions: - Mount the main repo dir at the path pointed at by the fake symlink. - Mount the main repo dir elsewhere, and rewrite the path in the fake symlink. - Replace the fake symlink with the dir it points at. It's possible that the solution could be more in `craft-providers` than `craft-application`. ### To Reproduce ``` $ cd ~/code $ git clone foocraft $ cd foocraft $ git worktree add ~/code/new-branch $ cd ~/code/new-branch $ snapcraft ``` ### part yaml _No response_ ### Relevant log output ```shell 2024-11-15 10:07:40.734 :: 2024-11-15 10:07:36.926 :: Successfully installed Deprecated-1.2.14
