The dataset-info plot now overlays every run as a separate named line instead of
replacing the plot when a snapshot is activated:
- Reader gains AllSnapshotDatasets() (every snapshot's dataset, Original first).
- The worker owns the run collection: a stable snapshot id plus an editable
display label (RunData), emitted as runsChanged(runs, active_id) on file open,
snapshot register, activate and rename. RenameRun(id, label) updates the legend
label without touching the reader key (decoupled id vs label).
- The chart view draws the active run as the primary series (markers, hover,
binning, axes) and the other runs as overlay lines sharing its axes, with a
legend shown when overlaying (appendSeries factored out for both).
- The dataset-info widget holds the run list + the live run, extracts the selected
metric from each (ExtractMetric), and unions the available metrics across runs.
- The live run is its own "Live" overlay (lightweight per-tick refresh, no combo
rebuild); it is cleared on finish so the persisted snapshot takes over.
- The processing jobs table gets a "Started" column and an editable Name column;
editing a name renames that run's legend label.
