refactor: Rename project and all internals to privlog

Completed a project-wide rename from 'logmaster' to 'privlog' for consistency with the published package name.

This includes:
- Renaming the source directory to 'privlog'.
- Renaming the rules file to 'privlog.yml'.
- Updating pyproject.toml to use 'privlog' for the package and script.
- Updating all internal imports and file paths.
- Deleting the old 'logmaster.egg-info' directory.
