feat: --info version-compare row; fix -i completion; release v1.2.6v1.2.6

--info/-i now prints a version-compare row between the header and the
README: SBo .info version vs the hint's, greening the higher side (< / >),
yellow on equal (=), '(no hint)' when no hint carries a version, skipped
when the .info has no version. Header stays pinned, version row scrolls
with the README.

Completion: -i now completes package names (was flag-only); package-name
completion for -n/-i drops the broken -maxdepth 2 .info scan for a
param-expansion sweep of REPO_DIR/*/*/ dirs, ~7s -> ~60ms.
