horizon-client, horizon-world and horizon-protocol each had an example named `probe`. Cargo copies every crate's examples into one <profile>/examples/ directory, so parallel parity harnesses sharing a target dir could run another crate's probe (CI parity run 40055656303: command_parse ran the horizon-world dispatcher). The examples are now client_probe, world_probe and protocol_probe ([[example]] in each Cargo.toml; the files stay where they are), and every harness builds and runs its own crate's name. tools/parity.py recognises the new names when it counts the probes a harness ran, and renames the old `probe` in recorded artifacts to the crate's target (from the record's -p, else its probe sources), so the prebuild still builds them instead of dropping them as unknown.
