feat(nushell): re-export completions for use-based startup

- switch completion module imports to export use so externs propagate

- extend managed completion command set and required file checks

- rename prompt static cache env var to PJ_LEFT_PROMPT_STATIC_PART

- load completion module via use in nu_polyjuice
