Review round 1, N2. The gameboy-decoder-config-v1 form (channels as ordered arrays), vectors for
raw mode and the Pokemon Red macro group computed by flysim's legacy_profile_identity test from
gameboy_decoder_config_with_macros and reproduced by @flybrain/session-types from the oracle's
gameboyDecoderConfig. The example composition now carries the real macros-mode digest and
channel set.
