fix(proto): align informer ProcessState widths with service.v1.Status; correct TCP PHP namespace

- informer/v1.ProcessState.pid: int64 → int32 (POSIX, matches service.v1.Status.pid)
- informer/v1.ProcessState.cpu_percent: double → float (matches service.v1.Status.cpu_percent)
- tcp/v1 PHP namespace: RoadRunner\Tcp → RoadRunner\TCP (matches HTTP/KV convention)

Surfaced by Copilot review on PR #74.
