/**
 * C149 — holds the google-calendar advisory lock for the WHOLE spec file
 * (`beforeAll` acquires on a dedicated connection, `afterAll` releases it).
 * Call at the top level of every int spec that touches the singleton
 * `googleCalendarSync` row so parallel files cannot read/write each other's
 * configured row.
 *
 * This module imports vitest hooks ON PURPOSE and must only be imported by
 * int specs: `tests/helpers/advisoryLock.ts` is also loaded by Playwright
 * fixtures, and pulling `vitest` into the e2e process breaks its matchers
 * (`Cannot redefine property: Symbol($$jest-matchers-object)`).
