   ### What would you like to happen?
   
   Context / Problem
   I need a transform that applies conditional rules (IF/ELSE) to rows in a 
pipeline. It should evaluate one or more input columns and, when a condition 
matches, update the value of one or more target columns. Today this typically 
requires chaining multiple transforms, which becomes hard to maintain, audit, 
and evolve.
   
   Goal
   Create a declarative, rule-driven transform to update column values at 
runtime in a pipeline.
   
   Functional requirements
   
   Allow configuring an ordered list of rules.
   
   Each rule must include:
   
   Condition: a boolean expression using row columns (e.g., colA = 'X' OR colB 
= 'Y').
   
   Actions: update 1..N columns with:
   
   a constant value, and/or
   
   the value of another column, and/or
   
   an expression (optional, if supported).
   
   Support rule application policy:
   
   FIRST_MATCH: apply the first matching rule and stop.
   
   ALL_MATCHES: apply all matching rules in order.
   
   Handle null values and basic type conversions (string/number/date) according 
to target columns.
   
   Provide clear configuration-time errors when a condition/action is invalid 
(e.g., missing column, type mismatch).
