Description

Live pipeline handle: push inputs in, pull outputs out.

A Run is what Graph::build() returns. It owns the live GStreamer pipeline plus its internal worker threads (typically 5–15 per Run, including streaming threads, dispatcher pool threads, and a bus watcher). Application code drives the Run by push()-ing inputs and pull()-ing outputs (or run() for one-shot synchronous use).

 auto run = graph.build(TensorList{input});

 run.push(TensorList{another_input});

 auto sample = run.pull(/ * timeout_ms = * / 100);

Thread safety: push() from one thread and pull() from another is safe. Multiple threads push-ing the same Run concurrently is NOT safe — serialize push from one thread or use external synchronization.

Runs are non-copyable but movable. Destroying a Run shuts down its pipeline cleanly (sends EOS, drains, transitions to NULL).
