// CANONICAL — twin of scripts/analytics/src/utils/storage.ts:getDataRoot.
// MUST STAY IN SYNC: identical default (~/.claude/linkedin-studio) + identical
// LINKEDIN_STUDIO_DATA override semantics. A twin exists (not a shared import)
// because the runtimes differ: hooks are plain .mjs run by Node with zero npm
// deps and cannot import the TypeScript module (which needs tsx). Change one →
// change the other; the twin-consistency test in __tests__/data-root.test.mjs
// guards the contract behaviorally.
