- load_file: use ObTextStringDatumResult to support out-row/LOB results instead of get_str_res_mem, avoiding size limits on large files - ai_split_document: add TO_STRING_KV for debug printing, mark expr as needing runtime context - resolver: return fixed column names (chunk_id/chunk_offset/chunk_length/ chunk_text) for T_FUN_SYS_AI_SPLIT_DOCUMENT function table, set implicit collation level for its text columns - deps: disable ob-deploy test-utils dependency
