chore: rehome to crudy/pgmorbac, align version to 0.1.0

Public home is now git.villains.fr/crudy/pgmorbac with docs at
pgmorbac.villains.fr. Point META.json, README and CHANGELOG links there,
drop the tracked .DS_Store, and renumber the first public release to 0.1.0
to match the published @crudy/pgmorbac package, the embedded framework SQL
and the download page. License stays MIT.
