Add compile-time step filtering based on formula variables:
- New EvaluateStepCondition function for {{var}} truthy and equality checks
- FilterStepsByCondition to exclude steps based on conditions
- Integration into pour, wisp, and mol bond commands
- Supports: {{var}}, {{var}} == value, {{var}} != value
Steps with conditions that evaluate to false are excluded from the
cooked formula, along with their children.
