Resolves the osrm-routed executable available on the current PATH
(or the override provided via options(osrm.routed.exec)). Runs
osrm-routed --version to verify availability, then prints the directory
containing the executable together with the backend version reported by
osrm-routed so you know what will be used in the current session.
Value
Invisibly returns a list with components executable (full path to
osrm-routed), directory (its parent folder), osrm_version (character
vector of non-empty lines emitted by osrm-routed --version), and the raw
processx::run result in logs.
