feat(data): read_parquet_15min + trader data_source(qfq/raw双源)
- datareader: +read_parquet_15min(sh/sz前缀+15min.parquet), get_database lazy(去tzlocal等依赖)
- data_source: iter_bars cross-section yield(date,{symbol:Bar}), raw首版fallback qfq+warning(spec§17)
- 本机 mock _read_fn 测调度逻辑, read_parquet_15min 容器冒烟 4 tests passed.
