refactor: apply check-ip CLI conventions to sibling cmds
Propagate the patterns used in cmd/check-ip to the other command-line
tools touched by this PR:

- flag.FlagSet + Config struct instead of package-level flag.String
  pointers (geoip-update, ipcohort-contains, git-shallow-sync).
- -V/--version/version and help/-help/--help handled before Parse,
  matching the project's CLI conventions.
- Stderr "Loading X... Nms (counts)" progress lines on the stages that
  actually take time: blocklist cohort parse (ipcohort-contains),
  per-edition fetch (geoip-update), and repo sync (git-shallow-sync).
  Stdout stays machine-parseable.
