actop 1.6.2

Fixed

• Export modes (--json / --serve) now honor --show-processes and
  --proc-filter — they were silently ignored, so every NDJSON record carried
  "processes":[] even when the TUI (t key) showed populated per-process data.
  The CLI routing (_run_export) now forwards both flags to the NDJSON and
  Prometheus backends; run_json_stream and serve_prometheus pass them through
  to Monitor(include_processes=True, process_filter=...). --proc-filter
  without --show-processes implies it, matching the Monitor's opt-in cost model
  where process collection stays off by default.
• Per-process Prometheus gauges (actop_process_cpu_percent,
  actop_process_cpu_time_share, actop_process_gpu_time_share,
  actop_process_attributed_watts, actop_process_rss_bytes,
  actop_process_num_threads): labelled by pid and command, emitted only
  when include_processes=True. The NDJSON path needs no format change —
  dataclasses.asdict already serialised processes when they were collected;
  the gap was purely that collection was never enabled.
