feat(team): add targeted runtime pid liveness check

resolveTeamMemberRuntimeLiveness принимает опциональный targetedProcess
с pid + command — если строка процесса проходит team/agent verification,
liveness отмечается как 'runtime_process' даже когда полная process table
не нашла его (например при гонке snapshot vs spawn). Дополнительно для
direct-process backend разрешён fallback по --agent-name, когда команда
запущена без --agent-id.
