Use built-in types rather than typing aliases for type annotations

[Copilot]

This PR modernizes the codebase to use built-in types instead of typing module aliases for type annotations, taking advantage of Python 3.9+ support for generic built-in types.

Changes Made

Type Annotation Modernization:

• Replaced typing.Tuple with tuple in all type annotations across Python and Cython files
• Replaced typing.List with list in all type annotations across Python and Cython files
• Removed unnecessary imports from the typing module
• Updated error messages to use consistent modern syntax

Files Updated:

• cuda_core/cuda/core/experimental/_memory.py - Updated Tuple annotations in Buffer methods
• cuda_core/cuda/core/experimental/_program.py - Updated List and Tuple annotations in ProgramOptions
• cuda_core/cuda/core/experimental/_system.py - Updated Tuple annotation in System.driver_version
• cuda_core/cuda/core/experimental/_linker.py - Updated List and Tuple annotations in LinkerOptions
• cuda_core/cuda/core/experimental/_stream.pyx - Updated Tuple annotations
• cuda_bindings/cuda/bindings/runtime.pyx.in - Updated 202 List/Tuple annotations in Cython template
• cuda_bindings/cuda/bindings/driver.pyx.in - Updated 261 List/Tuple annotations in Cython template
• cuda_bindings/cuda/bindings/nvrtc.pyx.in - Updated 10 List/Tuple annotations in Cython template
• cuda_bindings/cuda/bindings/_lib/utils.pyx.in - Removed unused typing imports and updated 1 annotation
• cuda_bindings/cuda/bindings/runtime.pxd.in - Updated all List annotations to list
• cuda_bindings/cuda/bindings/driver.pxd.in - Updated all List annotations to list

Linting Configuration:

• Enabled ruff rules UP006 and UP035 to enforce modern typing practices going forward
• Kept UP007 disabled to maintain Python 3.9 compatibility (union syntax X | Y requires 3.10+)

Example

Before:

from typing import List, Tuple, Union

def driver_version(self) -> Tuple[int, int]:
    """Query the CUDA driver version."""
    # ...

ptxas_options: Union[str, List[str]] | None = None

After:

from typing import Union

def driver_version(self) -> tuple[int, int]:
    """Query the CUDA driver version."""
    # ...
    
ptxas_options: Union[str, list[str]] | None = None

All changes maintain backward compatibility while modernizing the codebase for Python 3.9+. Variable names containing "List" or "Tuple" are preserved unchanged.

Fixes #891.

Good first pass, @copilot. You can also apply the same kind of changes to the Cython .pyx.in files in this repository.

Good first pass, @copilot. You can also apply the same kind of changes to the Cython .pyx.in files in this repository.

I've extended the typing modernization to all Cython .pyx.in files in the repository as requested. The changes include:

Files Updated:

• cuda_bindings/cuda/bindings/runtime.pyx.in - Updated 202 type annotations
• cuda_bindings/cuda/bindings/driver.pyx.in - Updated 261 type annotations
• cuda_bindings/cuda/bindings/nvrtc.pyx.in - Updated 10 type annotations
• cuda_bindings/cuda/bindings/_lib/utils.pyx.in - Removed unused typing imports and updated 1 annotation

Changes Made:

• Replaced List[...] with list[...] in all type annotations
• Replaced Tuple[...] with tuple[...] in all type annotations
• Removed List, Tuple from typing imports, keeping only Any, Optional where needed
• Updated error messages to reference the new modern types

All changes maintain the same functionality while using Python 3.9+ built-in generic types. The commit hash is 31b795d.

Fixed the missed Tuple annotation in cuda_core/cuda/core/experimental/_stream.pyx. Removed Tuple from the import statement and updated both Tuple[int, int] type annotations to use tuple[int, int] instead. Commit 4329941.

This is the same mistake of changing List to list as part of other words. Please go through all of the changes in this PR and make sure this mistake is corrected.

Fixed the variable name casing errors where List to list replacement incorrectly changed variable names like descList → desclist, opList → oplist, etc. The changes now only target type annotations while preserving variable names. Commit 37e37be.

@copilot: More CI errors. You need to update the tests that look at exception strings containing these type annotations to use the new style.

...

Fixed the exception string tests in cuda_core/tests/test_memory.py to use the modernized tuple[int, int] format instead of Tuple[int, int] in the pytest.raises patterns. This ensures the tests will pass with the updated type annotations. Commit f3213cd.

LGTM

LGTM! We need to backport the changes to cuda.bindings to the 12.9.x branch.
