feat: nvchecker autodetect expansion, -n stanza echo, --info/-i; release v1.2.5

Documents the Task 1-6 additions that shipped without doc updates: expanded
nvchecker source autodetection (gitlab, bitbucket, gitea, codeberg, pagure,
npm, gems, crates.io, cpan, hackage, packagist, cran, in addition to github
and pypi), the fenced stanza echo on --new/-n, and the --info/-i command
(category/program header plus paged README). Updates show_help, bash
completion, mkhint.1.md (rebuilds mkhint.1.gz), CLAUDE.md, and CHANGELOG.md.
Bumps MKHINT_VERSION to 1.2.5. No program logic changed; 224/224 tests still
pass.
