Summary:
Add a new static method experiment_status_from_generator_runs() to GenerationStrategy that extracts and validates a suggested ExperimentStatus from a list of GeneratorRun objects. It collects all unique suggested_experiment_status values from the runs and:

  • Returns None with a warning if there are conflicting statuses across runs
  • Returns None with an info log if no statuses are found
  • Returns the single agreed-upon status otherwise

Summary:

Add a new static method `experiment_status_from_generator_runs()` to `GenerationStrategy` that extracts and validates a suggested ExperimentStatus from a list of GeneratorRun objects. It collects all unique suggested_experiment_status values from the runs and:

- Returns None with a warning if there are conflicting statuses across runs
- Returns None with an info log if no statuses are found
- Returns the single agreed-upon status otherwise

Summary:

This change introduces an optional `suggested_experiment_state` field to
the `GenerationNode` class that allows tracking what experiment status is suggested
for a given generation node. This is part of a larger effort to add status tracking
to experiments.

The field is:
- Optional (defaults to None for backward compatibility)
- Advisory only (does not automatically update experiment.status)
- Configurable per GenerationNode instance
- Serialized automatically via SerializationMixin
- Displayed in __repr__ when set

This is Phase 1 where we are just adding the column but not yet doing anything with it. In the next diffs in this stack we will propagate this through the orchestrator and eventually set this status on the experiment.

Summary:

Set the `suggested_experiment_status` field on generation nodes throughout the codebase. This will be used in the next diffs in stack to allow the orchestrator to automatically update experiment status based on the optimization phase.

**Why this change:**
This builds on the infrastructure added in previous diffs which added the status field to Experiment, and GenerationNode. Now we're actually setting the field on nodes so that experiments will automatically transition through their lifecycle based on what GS node they're in.

Summary:

## Summary

Add `suggested_experiment_status` column to `GeneratorRun`. Some benefits:

1. We don't need to modify the GS.gen() or Orchestrator methods to pass along a suggested status via tuple, instead it's baked into the GeneratorRuns that are already being passed along
2. The suggested status are more clearly stored in the database for historical tracking

Prior to this approach I tried changing `GS.gen()` to return a tuple including the `suggested_experiment_status` but that over-complicated callsites.

Summary:

In the previous diff (D88091530) we added `suggested_experiment_status` the column to GeneratorRun, now we populate it during creation from GenerationNode.
