#17729: fix(configure): update web tools hint to reflect all search providers

Update the CLI wizard hint from 'Configure Brave search + fetch' to 'Configure web search provider + fetch' since OpenClaw now supports multiple search providers: - Brave (default) - Perplexity - Grok (xAI) - Parallel This is a minor UX fix to ensure the configure menu accurately reflects the available options. <!-- greptile_comment --> <h3>Greptile Summary</h3> Added Parallel as a fourth web search provider alongside Brave, Perplexity, and Grok. The implementation includes: - Full API integration with Parallel's search endpoint (`/v1beta/search`) - Configuration support for mode (`one-shot`/`agentic`/`fast`), result limits (1-20), and excerpt sizing - Updated CLI wizard to present all four providers with descriptive hints - Schema validation and type definitions for the new provider - Help text and documentation references The PR title mentions updating the configure hint, which was accomplished by changing "Configure Brave search + fetch" to "Configure web search provider + fetch" in `configure.shared.ts:55`. <h3>Confidence Score: 5/5</h3> - Safe to merge - well-structured feature addition with consistent type safety - The implementation follows existing patterns for other search providers (Perplexity, Grok), maintains type safety throughout with Zod schemas and TypeScript types, includes proper error handling, and updates all relevant configuration surfaces. The cache key issue mentioned in previous threads is a valid performance consideration but not a blocking issue. - No files require special attention _{Last reviewed commit: 74ca377} <!-- greptile_other_comments_section --> <!-- /greptile_comment -->
