Conversation
Adds a new system test file to verify that picosecond precision timestamps are correctly retrieved from BigQuery when using the Storage Read API with Arrow format and timestampOutputFormat set to STRING. This test ensures that data fidelity is maintained for high-precision temporal fields by avoiding conversion to native Arrow timestamp objects which only support microsecond precision in JavaScript.

Added a system test file
system-test/timestamp_output_format.tsthat verifies high-precision timestamp retrieval usingBigQueryReadClient. The test sets up a table with picosecond precision, inserts a high-precision timestamp, and reads it back using the Storage API with Arrow format, asserting that the value is returned as a string with the correct precision.PR created automatically by Jules for task 1177441700526495120 started by @danieljbruce
