Summary

• Per-worker execution stats: fan_out now captures %{node, duration_ms, ipc_bytes} per worker and attaches to meta.worker_stats
• Remove broken status(pool) overload: :pg doesn't propagate across FLAME nodes, so the pool-name discovery path always returned 0 workers. Only status(workers) with the list from spin_up works.

Usage

result = pipeline |> Dux.distribute(workers) |> Dux.compute()
result.meta.worker_stats
# => [
#   %{node: :"flame-abc@...", duration_ms: 1200, ipc_bytes: 42_000_000},
#   %{node: :"flame-def@...", duration_ms: 1400, ipc_bytes: 44_000_000},
#   ...
# ]

Dux.Flame.status(workers)
# => %{total_workers: 3, nodes: %{...}, worker_pids: [...]}

Test plan

• 42 tests pass (0 failures)
• Credo strict clean
• No performance cost — stats use O(1) operations on existing data
