  Log Message:
  -----------
  Lower iterator affinity subscripts and sections correctly

Teach OpenMP affinity lowering to evaluate iterator-dependent subscripts
through the iterator symbol mapping and use them to build the element
coordinate directly.

This fixes cases such as:
- affinity(iterator(i,j): a(j,i))
- affinity(iterator(i,j): a(i+1,j))
- affinity(iterator(i,j): a(i:i+1,j+2))
- affinity(iterator(i,j): a(:i+1,j+2))

  Log Message:
  -----------
  Handle dynamic affinity object sizes and improve iterator coverage

Teach task affinity lowering to compute lengths for dynamic objects
instead of falling back to zero for whole-object cases such as
assumed-shape, allocatable, pointer, character, and polymorphic type.

Add more tests in task-affinity
    - assumed-shape, allocatable, pointer, and polymorphic objects
    - character objects with constant and runtime length
    - iterator character element affinity
    - reordered, expression, and section iterator subscripts
    - Extract iterator handling from processAffinity
