SMB VFS: Add set_len, set_stat, streaming write, auto_reconnect
- set_len() via SMB SET_INFO compound (CREATE → SET_INFO → CLOSE)
with FileEndOfFileInformation (class 14)
- set_stat() via SMB SET_INFO compound with FileBasicInformation (class 4)
for timestamp updates (atime, mtime)
- Streaming write using Tree::create_file_writer + FileWriter::write_chunk
+ finish for pipelined uploads
- Add file_writer: Option<FileWriter> to SmbVfsFile for streaming state
- Enable auto_reconnect by default (new_with_options param)
- Add systemtime_to_filetime helper for timestamp conversion
All 229 tests pass.
