update the comments

**1. `open-sse/transformer/responsesTransformer.ts`**
- Removed `import { resolveDataDir } from "../../src/lib/dataPaths"`
- Restored: `typeof process !== "undefined" ? process.cwd() : "."`
- Added history comment: `// previous: const baseDir = logsDir || resolveDataDir(); — reverted in #555 for Workers compat`

**2. `open-sse/config/credentialLoader.ts`**
- Updated JSDoc with `resolveDataDir()` description
- Added history: `previous: Priority: DATA_DIR env → ./data (project root)`
