目标: Enable the channel feature in Cargo.toml to use http_body_util::channel::Channel, handle backpressure via try_send returning unsent frames, preserve pre-abort buffered frames before error, and configure Limited size limits without trailer truncation HOW

http_body_util::channel::Channel requires Cargo feature 'channel' (or 'full') as default features are empty
Channel::new(2) tracks remaining buffer capacity from initial max_capacity down to 0 on sends
Sender::try_send on full channel returns Err(Frame) preserving the unsent frame rather than dropping it
Channel::abort delivers all queued data frames before yielding the abort error
Sender::send_data and try_send fail with SendError when receiver is dropped
Limited::new(body, limit) rejects chunks exceeding remaining limit with LengthLimitError without chunk truncation
Limited exempts trailer frames from the data byte limit and passes them through after data limit exhaustion
Limited with limit 0 permits 0-byte frames but immediately rejects non-empty data frames with LengthLimitError
