M3/M4: interactive chart, checkpoints/generate/eval panel, crash recovery, watchdog
…
- TrainingChartView: hover crosshair with step/train/EMA/ppl/val callout, pinch-zoom + horizontal pan (chartScrollableAxes), follow-live pill that disengages on manual pan and re-pins to the latest data, double-click / fit reset, log-Y, best-val rule — replaces the static chart - CheckpointsPanel on finished runs: checkpoint list (step/size), Generate (prompt/temp/top-k, streamed output) and Eval (loss/ppl) via forge CLI - Crash recovery: runs persisted as active at launch are truthfully marked stopped, with the live-PID case called out; no lying states - Watchdog: 'possibly stalled' badge when a running run's log.csv stops growing for 30s - New Run: import/export Forge-compatible JSON configs Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
