pplx - Perplexity's web search and page-snippets CLI

What this skill does

Installs, authenticates, and drives Perplexity's public pplx CLI: pplx search web for live web search, pplx content snippets for query-relevant page excerpts. Output contract: success = exit 0 and exactly one JSON object on stdout; failures are pitfall 4.
