Brewcode Plugin Update

Check/install/update brewcode, brewdoc, brewtools, brewui. Run shell commands here; user-only /plugin UI/reload and marketplace-command acceptance are explicit handoffs, never invented tool actions.

Prompt contract

Position 1 of $ARGUMENTS is a free-form prompt (RU/EN) — the mode is optional and may follow in any order. Nobody types keys: resolve the mode FROM the prompt.

1. Strip flags. An explicit mode token anywhere wins outright, no scoring.
2. Else score modes by distinct whole-word keyword hits (table below). Highest unique score wins. All zero -> interactive.
3. Empty arguments -> interactive; check asks nothing (read-only). interactive asks its own per-phase AskUserQuestion gates — that IS the mode, not an extra clarifying question.
4. Outcome-changing ambiguity between update and all -> ONE AskUserQuestion BEFORE any work.
5. Prose that is not a mode is still input: read it for which plugins/scope it names.
