Replace per-chunk parse_sse_frames with SseParser holding raw bytes across chunks: reassembles frames split at TCP boundaries (the review's silently-losing case), decodes UTF-8 per complete line so multi-byte chars split across chunks survive, caps the buffer at 1 MiB (SSE_EVENT_BUFFER_CAP) and dispatches a pending event at EOF. forward_stream threads the parser through its unfold state and emits a terminal error envelope on cap overflow. Existing single-chunk SSE test assertions preserved; added multi-chunk, split-UTF-8, EOF-dispatch, and cap tests. Verified: cargo test (219 pass), clippy -D warnings, fmt --check.
