- sabnzbd-mcp: original upstream (jmagar/sabnzbd-mcp) was deleted from
GitHub (404). Repoint to jasonpaulso/sabnzbd-mcp fork, which preserves
the same file layout and the /sabnzbd/api string postPatch rewrites.
- annas-mcp: remove package that was never completed (lib.fakeHash
placeholders) and is not referenced anywhere in config-nixos. It was
breaking 'nix flake check'.
