Phase 1 of consolidating run-level config into the Builder UI. The
Builder UI's "Run Settings" section is now rendered at the TOP of the UI
(was previously below config arrays) and gains six new fields with help
tooltips:
- overwrite_existing (bool, default false)
- flush_batch_every (int, default 4)
- lora_triggerwords_mode (enum: None / Append To End / Append To Start /
Read From Config, default None)
- save_conditioning_cache_to_file (bool, default false)
- enable_model_cache (bool, default false)
- vae_batch_size (int, default 4, range -1..64)
State plumbs through state_to_configs_json -> _session_settings ->
sampler_node.run_tests -> run_generation_loop. Builder UI values
override the corresponding widgets on UltimateSamplerGrid when set
(non-default). Widget values remain the fallback so existing workflows
keep working without changes.
Logs an "⚙️ <name> overridden by Builder UI: <value>" line whenever an
override fires, so it's obvious in the console.
Next: once the user has tested this thoroughly, the corresponding
widgets on the SamplerGridTester node can be removed/hidden to
simplify the generator UX (deferred — coordinate with user).
