Move rules into db dep as it's useful for external apps

- rules is already used by logseq-query and will be useful for
  nbb-logseq
- Updated db jobs to run in deps/db by default. Less typing but
  more importantly discourages independent libraries from depending on
  external scripts.
- Moved lint-rules task into db since it is db specific now
- Also remove nbb-logseq from top-level as all nbb compatibility is in
  deps.
