pub trait TrialExecutor: Send + Sync {
    // Required method
    fn execute_trial(
        &self,
        params: &HashMap<String, Value>,
        ctx: &TrialContext,
    ) -> Result<TrialOutcome>;
}

Callback that executes a trial given sampled parameters.

Returns Ok(TrialOutcome) for normal completion or pruning, Err(SomaError) only for unexpected failures.

fn execute_trial( &self, params: &HashMap<String, Value>, ctx: &TrialContext, ) -> Result<TrialOutcome>

Run one trial with the sampled params, reporting intermediate metrics through ctx and honouring its pruning verdicts.
