horizon-mods' runtime is no longer a default feature, and its sandbox test requires runtime and pack instead of a dev-dependency on itself (that dev-dependency turned the runtime on in every workspace build with examples, the parity probe build included). The client gets a mods feature that turns the runtime on; without it game/mods.rs keeps content mods and logs why code mods don't start, and every hook does nothing. Release builds (client and server) pass the feature, CI's clippy and tests pass it (and pack, for the sandbox test), and pr_ready does where horizon-mods is checked. horizon_mods::find moves to manifest.rs: content mods use it without the runtime.
