Add python min/max syntatic sugar

[gordonwatts]

Motivation

• Make behavior explicit in docs that builtin min/max called with a single list/generator comprehension lowers to Min(...)/Max(...) so aggregate simplification can process them.
• Add tests to cover both successful lowering and invalid signature cases for min/max when used with comprehensions.

Description

• Added _resolve_min_max_call to func_adl/ast/syntatic_sugar.py to detect min/max calls on comprehensions, validate signatures, and return Min(...)/Max(...) AST calls.
• Wired the new resolver into the call handling in resolve_syntatic_sugar so it runs after the existing any/all lowering.
• Updated documentation in README.md and docs/source/generic/query_structure.md to describe the min/max lowering and show an example aggregate-form rewrite using Max(...).
• Extended tests/ast/test_syntatic_sugar.py with positive tests for min/max lowering and additional negative tests asserting invalid signatures raise ValueError.

Testing

• Ran pytest -q tests/ast/test_syntatic_sugar.py and it succeeded (46 passed).
• Ran the full suite with pytest -q and it succeeded (438 passed).
• Ran black --check func_adl tests and it succeeded, while black --check that included README.md and the modified markdown docs failed due to Black parsing those markdown files as Python (markdown files are not targeted by black), so code and tests remain formatted.
• Ran flake8 func_adl tests and it succeeded with no issues.
