- Flattened radio/ directory to radio.rs (was just one file) - Flattened display/ to display.rs (combined task + rendering as inline module) - Moved SH1106 display driver reference from display/ to driver/ (done in Phase 2) - Suppressed dead_code warnings for conditional USB/UART types in hal - All boards: zero warnings, zero cfg in application code
