/**
* TDD regression for #5312 (FIX A / RC-A wiring): hydrateThinkingBudgetConfig was
* only called from `src/server-init.ts`, which is an UNUSED module that never runs
* in production (the live boot path is the Next.js instrumentation hook →
* `src/instrumentation-node.ts`). As a result the operator's dashboard
* Thinking-Budget mode silently reverted to the passthrough default on every
* restart, even though the unit test `thinking-budget-hydration-5312` (which calls
* the function directly) passed. Surfaced by live VPS validation of #5312.
*
* This guard asserts the LIVE boot module actually calls the hydration, so the fix
* can never again be wired into dead code without a failing test.
