BlackMarkandClaude Opus 5.5 f9bc2cd8e2 refactor: one alarm encoder, named register bits, and the example 14 B smaller ...

Both alarms' registers come from one encoder that derives DY/DT and the
mask bits from the rate, and the battery checks the bytes each Table 2
row writes instead of restating the enum values. Register addresses and
bits are named, the year register is the year less 2000 rather than a
division, and an alarm day reads back with one decode for both forms.
Over the whole API the image is 10 B smaller on both parts; a rate only
known at run time costs set_alarm1 6 B more.
