Fixes #4733 PyArrow expects Blob V2 storage structs when constructing a record batch and cannot infer the extension array from raw bytes. LanceDB already converts binary values during ingestion, but batch writers had no supported array constructor. Add `lancedb.schema.blob_array(payloads)` for iterables of inline bytes and nulls, using the same extension type resolver as `blob()`. The helper preserves empty blobs and null blobs and works with both pylance's type and LanceDB's fallback. Document the descriptor fields, exclusive inline/external representations, batch construction, and existing binary conversion in synchronous and asynchronous `create_table` / `add` APIs. Validation: - Reproduced the reported `ArrowTypeError` on the original code; both new regression cases fail against the original schema module. - 256 focused blob tests and schema doctests passed; one optional PyAV test skipped. - Both new regression cases also passed with PyArrow 25, with and without pylance imports. - Python package Ruff checks and formatting passed. - MkDocs build passed, with an existing unrelated `SecretReference` cross-reference warning. Repository-wide Ruff reports 48 existing errors in `docs/web-tests`. <!-- lance-gatekeeper-fix:v1 agent=20d1a296d76ff5eb914c0848428a747a generation=1 --> Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com>
