fix(pre-commit): normalize SPDX handling

[bdice]

Description

Contributes to rapidsai/build-planning#303.

Standardizes clang-format's SPDX protection and ensures the repository uses rapidsai/pre-commit-hooks v1.6.0. It also restores malformed SPDX headers where present.

Validated with pre-commit run --all-files.
