Assign per-instance TensorBoard ports from session_state registry#280

Each panel instance now reads COMET_PANEL_INSTANCE_ID and uses a shared session_state dict to claim a unique port in the range 6000-6009, rather than all instances hardcoding port 6007. Raises RuntimeError if all 10 ports are exhausted. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…e experiment objects Streamlit deepcopies session state when registering widgets, which fails when experiment objects contain thread locks. Replace direct selectbox usage with a select_experiment() helper that stores only a picklable integer index and looks up the experiment by position.
