Subject: [PATCH] perf: skip dict copy for non-compression auxiliary calls

_compression_fast_lane_controls unconditionally did body = dict(extra_body)
before the early-return guard. Move the copy below the guard so non-
compression auxiliary calls (vision, title_generation, etc.) return the
original extra_body reference without a shallow copy.
