Function get_worktree_root 

pub fn get_worktree_root(cwd: &Path) -> Option<String>

Get the worktree root path if the current directory is within a git worktree.

Returns the absolute path to the worktree root (the directory containing the .git file that points to the worktree’s git directory).

Returns None if:

• The directory is not in a git repository
• The directory is in a normal git repository (not a worktree)

Example

use std::path::Path;
use mi6_core::context::get_worktree_root;

// In a worktree: returns "/path/to/worktree"
let root = get_worktree_root(Path::new("/path/to/worktree/subdir"));

// In a normal repo: returns None
let root = get_worktree_root(Path::new("/path/to/normal/repo"));
