📝 Walkthrough

Summary by CodeRabbit

Bug Fixes
- Improved compatibility and reliability for GPU reduction-by-key and scan operations by updating internal kernel parameter handling.
Refactor
- Simplified internal kernel declarations without changing user-facing functionality or behavior.

Walkthrough

The PR removes _CCCL_GRID_CONSTANT qualifiers from parameters in DeviceReduceByKeyKernel and DeviceCompactInitKernel. Kernel dispatch and implementation logic remain unchanged.

Changes

Kernel signature updates

Layer / File(s)	Summary
Reduce-by-key kernel signature `cub/cub/device/dispatch/dispatch_reduce_by_key.cuh`	`DeviceReduceByKeyKernel` parameters now use plain `const` declarations instead of `_CCCL_GRID_CONSTANT`.
Compact initialization signature `cub/cub/device/dispatch/kernels/kernel_scan.cuh`	`DeviceCompactInitKernel` declares `num_tiles` as plain `const int`.

Assessment against linked issues

Objective	Addressed	Explanation
Fix the `reduce_by_key` regression in CCCL 3.4 [`#9822`]	✅

Assessment against linked issues: Out-of-scope changes

Code Change	Explanation
Remove `_CCCL_GRID_CONSTANT` from `DeviceCompactInitKernel` (`cub/cub/device/dispatch/kernels/kernel_scan.cuh:111-112`)	The linked issue specifically concerns the `reduce_by_key` regression; no connection to `DeviceCompactInitKernel` is stated.
