Commit Message

fix(stress): disable metrics exporter in spawned process-topology nodes (#610)

The tsoracle binary, when built with the `metrics` feature, installs a
Prometheus exporter on a hardcoded 127.0.0.1:9551 by default. The stress
process-topology harness gives each spawned node a unique --listen port
but not a unique metrics port, so whenever two instances are alive at
once on one host the second fails to bind 9551 (EADDRINUSE) and aborts
startup.

This surfaced on the `test` CI lane (cargo test --workspace
--all-features), which compiles the binary with `metrics` enabled:
cargo's default test parallelism runs the process smoke tests
concurrently, and the killer-loop scenario also respawns nodes before
the killed socket is reaped. Either path collides on 9551.

The harness scrapes no metrics, so spawned children should not run an
exporter. Pass --no-metrics when spawning. Because other lanes build the
binary without the `metrics` feature and run the same spawn code, the
flag is ungated so it parses in every build (documented no-op without
the feature); --metrics-listen stays gated. A unit test guards that
--no-metrics parses without the feature.
