Awwwards MCP Setup

First-time onboarding for the awwwards MCP server. Goal: before the first real search, know how this user wants results served, and have the optional heavy deps installed only if they'll be used. Every choice is persisted, no choice is re-asked.

0. Check for existing preferences

Read ~/.awwwards-mcp/preferences.json (cache dir may be relocated via AWWWARDS_CACHE_DIR — respect it if set). If the file exists and names the fields below, apply it silently and stop — do not re-onboard. If a field is missing, ask only about that field. If the file is absent, proceed.
