/**
 * tests/v4/core/webSearchDebugGate.test.ts — Phase v4.1.5 Issue O.
 *
 * Verifies the `AIDEN_DEBUG_WEB` env-var gate on the `[webSearch]` /
 * `[deepResearch]` debug lines in `core/webSearch.ts`. Default OFF
 * (clean output); set to `'1'` to enable.
 *
 * The helpers live in `core/webSearch.ts` but they're not exported.
 * We test them by triggering the public surface (`reliableWebSearch`)
 * with a guaranteed-fail config and capturing the console output.
 * Set `SEARCH_TIMEOUT` low and point at unreachable hosts so each
 * fallback fires its `debugWarn(...)` quickly.
