fix(clang-format): preserve SPDX comments

[bdice]

Description

Contributes to rapidsai/build-planning#303.

This updates clang-format's CommentPragmas to preserve SPDX copyright and license lines. Without this, clang-format reflows the canonical notice produced by verify-copyright, so consecutive pre-commit runs keep modifying the same block comment. Where a header was already corrupted, this also restores its canonical two-line form.

📝 Walkthrough

Walkthrough

Updated formatter and pre-commit configuration, normalized SPDX header formatting across production and supporting files, and added a targeted hardcoded-version check suppression in the regression configuration.

Changes

Header and tooling alignment

Layer / File(s)	Summary
Formatter and pre-commit configuration .clang-format, .pre-commit-config.yaml	Updated SPDX/IWYU comment matching, bumped the RAPIDS hook revision, and added a documentation-path exclusion.
Production SPDX header normalization cpp/include/..., cpp/src/...	Reformatted or condensed SPDX copyright and license headers without changing implementation code.
Test, documentation, and script headers cpp/tests/..., docs/cuopt/..., regression/config.sh	Normalized SPDX headers and added a targeted hardcoded-version suppression for the regression script.
