Streaming write: 3x faster, remove per-packet backpressure#35
Conversation
With COBS trailing zero bug fixed + D-cache enabled, per-packet ACK is no longer needed. Pure streaming at 921600 baud: Before (per-packet ACK): 16MB in 9 min (30 KB/s) After (streaming): 16MB in 3.5 min (77 KB/s) Selfupdate also switched to streaming mode. Verified: 16MB CRC32 match on hi3516ev300. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Summary
Remove per-packet backpressure ACK from WRITE, SELFUPDATE, and FLASH_WRITE handlers. With the COBS trailing zero bug fixed (PR #20) and D-cache enabled, the agent processes packets fast enough to keep up with 921600 baud without flow control.
