[ci] add CMake linting/formatting, update pre-commit hooks, re-arrange modules

[jameslamb]

Just some minor maintenance, ahead of some more active development here.

• adds CMake linting (cmakelint) and auto-formatting (cmake-format)
• updates all pre-commit hooks with pre-commit autoupdate
• changes the module names of all modules except pydistcheck.cli, to even further hide them and discourage their use, inspired by this new error from ruff:

ruff.....................................................................Failed

src/pydistcheck/inspect.py:1:1: A005 Module `inspect` shadows a Python standard-library module
