docs(kyberforge): add keywords/homepage/repository to plugin apm.yml

bin and kyberforge had empty keywords: [], and no plugin set homepage or
repository despite the schema supporting both and the repo having one
canonical Gitea remote -- flagged by an apm-docs-vs-repo audit following
issue #90's plugin->apm conversion.

Compiled .claude-plugin/plugin.json and .github/plugin/plugin.json were
regenerated via scripts/sync-plugin-content.sh to carry the new fields.
