Puppet modules can only be proxied from a remote Forge; there is nowhere to publish internal modules for puppet module install, r10k and g10k.
- add puppet local uploads at <owner>-<module>-<version>.tar.gz, rejecting existing versions
- record each release's metadata.json, md5 and sha256 in a puppet_metadata table, streaming the tarball under size caps
- serve Forge v3 /v3/modules, paginated /v3/releases, /v3/releases/<slug> and /v3/files
- add an e2e-docker case driving real r10k and puppet module install
- document local puppet in README and UI usage snippets
