/**
 * Direct REST client for https://api.exa.ai/search.
 *
 * P3 of the pi-exa-search review: switch websearch (and codesearch)
 * to direct REST for full feature access (searchType, recencyFilter,
 * domainFilter, highlights, etc.) while keeping the existing MCP
 * path as a zero-config fallback.
 *
 * Code adapted from najibninaba/pi-exa-search's exa-client.ts,
 * re-typed against our shared `types.ts`.
