Pull request overview

Fixes FlyDSL’s divide-family semantics to align with CuTe/CuteDSL, addressing Issue #739 where zipped_divide could crash (notably with None elements in the tiler and when tiler rank < layout rank).

Changes:

• Update Python divide wrappers to accept “bymode” integer divisors and route divisors through a unified coercion helper.
• Fix C++ layoutZippedDivide / intTupleZip2By handling of None tiler modes to avoid rank-2 terminal assertion failures and match expected (1,s):(0,d) behavior.
• Add unit tests covering logical_divide, zipped_divide, tiled_divide, and flat_divide for int, 1D tilers, and tilers containing None.

File	Description
tests/unit/test_layout_algebra.py	Adds regression/behavior tests for divide variants across bymode/int and None tiler cases.
python/flydsl/expr/primitive.py	Changes divisor coercion for divide APIs; introduces _make_tile_or_layout and updates make_tile singleton handling.
include/flydsl/Dialect/Fly/Utils/LayoutUtils.h	Updates zipped-divide guide construction and passes distinct noneValue for shape vs stride.
include/flydsl/Dialect/Fly/Utils/IntTupleUtils.h	Extends intTupleZip2By to handle None guides explicitly and prevents problematic singleton-guide unwrapping.
