*PARSES GROUP_DEFINE PARAMETERS FROM MADYMO*
============================================

Parses GROUP_DEFINE blocks from a Madymo input file supplied as raw text, extracting VAR_NAME and VALUE attributes into a structured parameter dataset. Use this worker to programmatically inventory or sweep Madymo model parameters before a design-exploration or deck-authoring step.

Inputs

     - Default
     - Required
     - Description
   * - MFIAT
     - file_input_text
     - textarea
     - —
     - ✓
     - Full Madymo input file pasted as plain text (textarea); must contain at least one GROUP_DEFINE block — this is the only required input.
   * - Constants
     - constants
     - scalar
     - —
     - 
     - Optional comma-separated list of VAR_NAME identifiers to treat as fixed constants and exclude from the extracted parameter set; leave blank to include all discovered parameters.
   * - Min Percentage
     - min_percentage
     - scalar
     - 80
     - 
     - Lower bound for each extracted parameter expressed as a percentage of its nominal VALUE (e.g., 80 = 80 %); defaults to 80 — used downstream for range sweeps.
   * - Max Percentage
     - max_percentage
     - scalar
     - 120
     - 
     - Upper bound for each extracted parameter expressed as a percentage of its nominal VALUE (e.g., 120 = 120 %); defaults to 120 — used downstream for range sweeps.
   * - Step Percentage
     - step_percentage
     - scalar
     - 20
     - 
     - Increment step between min and max bounds expressed as a percentage of the nominal VALUE (e.g., 20 = 20 %); defaults to 20 — used downstream to define discrete sweep steps.

     - parameters
     - dataset
     - Tabular dataset of extracted GROUP_DEFINE parameters, with columns for VAR_NAME, nominal VALUE, and (when range inputs are provided) the computed min, max, and step bounds — consumed by deck-authoring or DOE workers.
