feat: add smoker recipe for Perl CI smoke testing

[troglodyne-bot]

What

New Provisioner::Recipe::smoker that provisions a machine capable of
cloning and smoke-testing ExtUtils::MakeMaker-based Perl repos.

Why

Troglodyne-Internet-Widgets repos (tCMS, tPSGI, …) need a repeatable CI
smoke environment. This recipe gives you a provisioned host that clones
any list of repos and runs the standard perl Makefile.PL && make test
workflow, including all native deps the XS modules require.

How

• lib/Provisioner/Recipe/smoker.pm — new recipe. Accepts a repos
  list (shortnames like Troglodyne-Internet-Widgets/tCMS or full HTTPS
  URLs), normalises them to full URLs, extracts clone-dir names, and defaults
  basedir to /opt/smoke. System deps cover the full XS build stack
  (SQLite, libmagic, libxml2, OpenSSL, seccomp/inotify, etc.).
• templates/smoker.tt — makefile fragment that clones (or git pull --ff-only) each repo and then calls smoke_perl_modules.pl with the
  right cpanm (prefers the custom perl from the perl recipe, falls back
  to system cpanm).
• scripts/smoke_perl_modules.pl — updated to run the proper MakeMaker
  workflow: cpanm --installdeps, perl Makefile.PL, make test.
  Previously used prove -vm t/ which bypassed the generated Makefile.

Example recipes.yaml snippet

smoker.example.test:
    smoker:
        repos:
            - Troglodyne-Internet-Widgets/tCMS
            - Troglodyne-Internet-Widgets/tPSGI
        basedir: /opt/smoke

Testing

• perl -Ilib -c lib/Provisioner/Recipe/smoker.pm — syntax OK
• perl -c scripts/smoke_perl_modules.pl — syntax OK
• Template reviewed against tabinate behaviour and existing patterns
  (koan.tt, tpsgi.tt) for correct $$VAR escaping in make context.

This is not useful compared to what Provisioner::Recipe::admincode provides.

What would be useful is something that looks at the provided CPAN users (such as me, TEODESIAN) and scrapes out the repo urls from the meta.yml in their dist tarballs, clones all of them and then smokes, with the option to report to cpantesters.
