Request

36140bf adds support for running clang-tidy through task and in the GH workflows.
Currently, the task lint:check-cpp-static-full succeeds thanks to an exclude list that skips all files with known clang-tidy issues (see https://github.com/y-scope/clp/blob/main/lint-tasks.yml for the task and exclude list).

The goal is to fix all the clang-tidy warnings and errors so that lint:check-cpp-static-full can succeed without the need for an exclude list.

Possible implementation

When you create a PR fixing clang-tidy issues:

1. Link to this issue for tracking.
2. Remove the file from lint:check-cpp-static-full's exclude list.
3. Comment on this issue, documenting any difficult fixes or discussion/guidelines that resulted from fixes.
