pub fn find_omne_root(start: &Path) -> Option<PathBuf>Expand description
Walk up from start looking for an ancestor that contains a
.omne/ subdirectory. Returns the first match, or None when the
walk reaches the filesystem root without finding one.
start is canonicalized first so relative paths, .. segments,
and symlinks are resolved before the walk begins. If start does
not exist or cannot be canonicalized, the function returns None
— the caller surfaces this as CliError::NotAVolume at the
command boundary.
