/**
 * discover_tools Tool
 *
 * Meta-tool for progressive tool discovery.
 * Enables models to search and explore available tools by category or keyword.
 * Reduces initial context overhead by allowing on-demand tool loading.
 *
 * Use cases:
 * - Discover available capabilities before making specific tool calls
 * - Filter tools by category (vault, portfolio, analytics, etc.)
 * - Search for tools by keyword in names or descriptions
 * - Get tool input schemas for specific tools
 *
 * Performance: ~100-200 tokens per query. No caching needed (static data).
