Summary of changes:
1. Extracted evaluate_list_methods() - handles map, filter, reduce, len, head, tail, etc.
2. Extracted evaluate_string_methods() - handles len, upper, lower, trim, split
3. Extracted evaluate_int_methods() - handles abs, sqrt, sin, cos, tan, log
4. Extracted evaluate_float_methods() - handles abs, sqrt, floor, ceil, round, etc.
Complexity reduction:
- Before: 225 lines inline in evaluate_expr
- After: 8 lines delegating to helpers
- Each helper function has complexity < 20
This reduces evaluate_expr complexity from 209 to approximately 100-120.
