* feat: implement Apache Arrow and Feather file ingestion support (#235)
* fix(arrow): eliminate double full-scan and clean up reader wrapper
- Replace _read_batches with _read_batches_with_info which collects
batch metadata (total_rows, record_batches) during the same pass as
the data read, so ingest_file no longer calls _file_metadata before
_read_batches. For a limit=1 read on a large file this previously
scanned every batch twice; now it stops after the first batch.
- _file_metadata is now only invoked for include_data=False (where a
full scan is unavoidable to report accurate row counts).
- Remove the dead num_record_batches property from _ArrowReaderWrapper;
it was never called by production code and its is_table branch
materialised all batches just to count them.
- Fix _open_file exception chain: raise ... from file_err instead of
from feather_err so the most diagnostic IPC error appears in the
Python traceback chain, not the least informative fallback error.
* docs(changelog): add [Unreleased] entries for Arrow ingestion (#705)
