fix(git): improve parsing of worktree list

[hiddeco]

This changes the listing of Git worktrees by implementing a more robust parsing mechanism for the git worktree list command output. The previous implementation struggled with certain edge cases, such as detached HEAD states, leading to parsing errors:

error adding work tree ./target to repo https://example.com/org/repo.git: unexpected number of fields: "/tmp/dir/source                67286d2 (detached HEAD)"

The new approach utilizes the --porcelain option and introduces a line-by-line parsing strategy, capable of extracting detailed information about each worktree, including its path, HEAD commit, branch, etc. without relying on a specific number of columns.
