Function stabilize 

pub fn stabilize<State, B, U>(
    initial: State,
    barrier: B,
    updater: U,
    params: &StabilityParameters,
    max_attempts: usize,
) -> Result<StabilizationResult<State, CorrectionDirectionSet, Evidence>>
where
    State: Clone,
    B: FnMut(&State) -> AgentBarrierResult,
    U: FnMut(State, &BarrierResult<CorrectionDirectionSet, Evidence>) -> SrbnResult<State>,

Drive the kernel’s srbn::stabilize loop over an arbitrary state, with the barrier producing an AgentBarrierResult (mapped to the kernel result).

Returns the kernel’s srbn::StabilizationResult so callers can serialize the attempt trace through srbn_serde into the ledger.
