Capture the FTP Session Log

Demonstrates the SessionLog property (with KeepSessionLog), which holds the in-memory FTP protocol conversation — commands and server replies — collected during the session.

Background: When an FTP operation fails for a non-obvious reason, the exact command/reply exchange is the most useful diagnostic there is, and SessionLog captures it verbatim once KeepSessionLog is enabled. Passwords are omitted, so it is safe to log or attach to a bug report. Over a long session it grows without bound; clear it with ClearSessionLog to bound memory or to isolate the log for one operation.
