Function replace_worktree_file 

pub fn replace_worktree_file(
    destination: &Path,
    bytes: &[u8],
    git_mode: &str,
    original: &[u8],
    identity: &WorktreeFileIdentity,
) -> Result<bool, RecoveryError>

What: Replace one unchanged worktree file through a same-directory temporary file; returns whether it was installed without an observed conflict. Why: replaceWorktreeFile: the destination is checked again after the replacement is ready.

In TS you’d write (pseudocode):

async function replaceWorktreeFile({ destination, bytes, mode, gitMode, original, identity }): Promise<boolean>;
