Add Feynman-Kac Control (FKC) steering denoiser and supporting components: Source code: - steering/dpm_fkc.py: FKC steered denoiser with analytical Girsanov weights - steering/collective_variables.py: Add RMSD, FractionNativeContacts CVs - steering/potentials.py: Add LinearPotential - steering/utils.py: Add compute_sequence_alignment, kabsch_align - denoiser.py: Add GuidedScore dataclass for FKC pre-scaled scores - config/steering/cv_steer.yaml: FKC steering config example - toy_gmm.py: 1D Gaussian mixture model for toy examples Examples: - notebooks/fkc_steering.py: FKC steering toy demonstration - notebooks/gmm_umbrella_mbar.py: GMM umbrella sampling with MBAR analysis Tests: - test_integration.py: FKC integration, ODE consistency, cv_steer config tests - test_potentials.py: LinearPotential unit tests - test_utils.py: Sequence alignment tests - test_steering_numerically.py: Numerical validation on GMM Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
