v0.1.4

Added

• Dispatch observability. DispatchSolution now carries stage-failure
  diagnostics and per-period AC-OPF statistics, making multi-stage workflow
  failures and AC-SCED iteration costs inspectable without re-running the
  solve.
• SCUC loss-factor warm start and per-period load-pattern sensitivity
  in surge-dispatch SCUC — reduces MIP root relaxation time on
  loss-aware formulations. Loss-factor coefficient writes now use a 1e-4
  cutoff to keep the LP sparse.
• Flowgate directional slack on surge-network::Flowgate — lets
  flowgate limits be relaxed in one direction without disabling the
  constraint.
• HiGHS MIP trace. MipTrace is now populated unconditionally on every
  HiGHS MIP solve (previously gated); primal bound recovery falls back to
  objective_function_value when mip_primal_bound is NaN.

Fixed

• GO C3 adapter: new market-extras fields are now forwarded into
  run-report.json.
