feat(completion): tag four pickers with categories for marginalia

Add cj/completion-table (and an annotated variant) to system-lib: a wrapper that tags any collection with a completion category so marginalia, embark, consult, and sorting can recognize the candidates. None of the config's completing-reads declared a category, so the rich-candidate pickers showed bare. This applies it to the four whose candidates match a standard category and so need no custom annotator: benchmark-method (function), ERC buffer switch (buffer), ai-term close (buffer), and theme switch (theme). Each now annotates for free.
