pub fn find_oxibrain_binary() -> Option<PathBuf>Expand description
Locate the oxibrain binary: the ecosystem-standard managed install
(~/.oxi/oxibrain/bin/oxibrain) first, then ~/.cargo/bin
(cargo-installed), then PATH.
If the binary resolves at the managed location and shows up in a
cargo bin or PATH entry as well, [warn_shadowed_roots] logs the
shadowed path names once per process so the operator can clean them
up (cargo uninstall oxibrain-cli, or rm <path>).
