pub fn find_daemon() -> Result<PathBuf, String>Expand description
Finds the choir-node binary.
Beside this executable first, PATH second. The sibling wins
because the two binaries are built and installed as a pair: an older
choir-node earlier on PATH would serve a different build than
the choir that launched it, and every symptom afterwards would
look like the running node being wrong rather than being old.
