Drop postcard and serde dependencies entirely. All integers are now fixed-width little-endian on the wire — no varints, no zigzag encoding. A developer sending tx_power_dbm=14 sees 0x0E on the wire. No surprises. - RadioConfig: 10 bytes fixed (freq:4 LE, bw:1, sf:1, cr:1, sync:2 LE, pwr:1) - Commands/Responses: tag byte + fixed-size fields - Vec<u8>: 2-byte LE length prefix + raw bytes - Option<T>: 1-byte (0=None, 1=Some) + T - COBS framing preserved (just byte-stuffing, no encoding tricks) - Manual COBS decode replaces postcard's CobsAccumulator - Removes ~15KB from firmware binary (no serde monomorphization)
