procscope v0.2.1 — repo plumbing

Mirroring to GitLab and Codeberg on every push, archiving to the Wayback
Machine / Software Heritage / archive.org for tags and the default branch,
issue pull-back from both mirrors every six hours, and collaborators-only pull
requests. Cron minutes staggered against the sibling repos.

pre-commit.sh runs make lint && make test-coverage.

No library code changed. The README's logring example is updated for
slog-configurator v1.4.0, where Search returns a Page.
