Function _ue_field_name

Scripts/codegen/generate_ue_components.py:2830–2836

snake_case mjxmacro name -> PascalCase UE field. Preserves URLab's naming convention from the hand-written MjSimOptions.h (ls_iterations -> LsIterations, ccd_iterations -> CCD_Iterations is a deliberate one-off — synthetic_categories rules can override via field_renames).

class EmissionPhase:
    """One step in the codegen pipeline. Phases are run in order; each
    either appends to ``ctx.writes`` (emit phases) or has side effects
    only (the diagnostics phase). The registry below makes adding a
    phase a one-line insert rather than another `writes.extend(...)`
    block in ``collect_all_writes``.
