Ludovic MarieandClaude Opus 5.5 0b581f9ffe Give each crate's probe example its own target name
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.
