Docker patches: goroutine leak fix + root schema repetition config#1
Conversation
Add write.parquet.root-repetition property (required/optional/repeated, default: required) to control the Parquet root schema element's repetition type. arrow-go defaults to Repeated, which Snowflake interprets as one-level list encoding and rejects files with list columns. Defaulting to Required aligns with the Parquet spec and matches arrow-rs, pyarrow, and parquet-java behavior.
iter.Pull(args.counter) was called unconditionally, but in the partitioned path newWriterFactory creates its own iter.Pull and the original stopCount was never called, leaking one goroutine per write. Move iter.Pull into the unpartitioned branch where it is actually used. Add a regression test confirming goroutine count stays stable.
