Subject: [PATCH] debug(rdp): enable guacd debug logging + log all guacd
 responses
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

guacd was dying silently with no error instruction sent back.
Enable -L debug -f for verbose FreeRDP diagnostics and log
first 5 guacd→browser instructions plus connection parameters.
