Merge pull request #144 from ripta/cg

pkg/cg: Command Guard

2026-01-05:

- Move to YYYY.MM.##, where ## is the number of releases in the month.
  Turns out, I release in bursts; the days were lies anyway once I
  release two in a day.
- Add togglecase (`toggle` in `uni map`).
- Introduce `(pkg/version).Get()` as a shortcut to get version
  information from outside of `rt`.
- Regular deps upgrades.
