Subject: [PATCH] fix: use explicit snake_case serialization for
 CompressionType
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Per project convention, enum string representations should use
snake_case. Use explicit strum serialize attributes instead of
serialize_all to avoid incorrect splitting of acronyms like
GZip → g_zip and ZStd → z_std.
