- `get()` now delegates to `bulk_get([url])[0]` (was a separate sync implementation)
- `fetch()` now delegates to `bulk_fetch([url])[0]` (eliminated duplicate fetcher call)
- `stealthy_fetch()` now delegates to `bulk_stealthy_fetch([url])[0]` (same)
- Replaced 6x repeated `_content_translator(Convertor._extract_content(...), page)` with a single `_translate_response()` helper
- Removed unused imports (`Fetcher`, `DynamicFetcher`, `StealthyFetcher`, `Generator`)
