Move the guix package list into manifest.scm

Message

The CI config carried its native dependencies inline in the shell command. That put the package set somewhere it could not be reviewed as code, reused locally, or changed without editing a quoted string inside a pipeline definition.

manifest.scm is already the estate convention -- 71 repos carry one -- and this repo was simply missing it. The pipeline now runs guix shell -m manifest.scm, so a developer reproduces CI's environment with the same file rather than by copying a command out of the config.

Verified by running the exact command the config now runs: 17 passed.
