030838cfde Implement computed range expansion for loops (gt-8tmz.27)
Add support for for-each expansion over computed ranges:

  loop:
    range: "1..2^{disks}-1"  # Evaluated at cook time
    var: move_num
    body: [...]

Features:
- Range field in LoopSpec for computed iterations
- Var field to expose iteration value to body steps
- Expression evaluator supporting + - * / ^ and parentheses
- Variable substitution in range expressions using {name} syntax
- Title/description variable substitution in expanded steps

Example use case: Towers of Hanoi formula where step count is 2^n-1
