Package streaks is an on-chain habit-streak tracker. Call CheckIn() again within graceBlocks of your last check-in and the streak keeps growing; let the gap run past that and it resets to zero on your next check-in. Gno has no wall clock, so "again soon enough" is measured in blocks rather than calendar days — graceBlocks is the tunable stand-in for "before tomorrow".
CurrentStreak returns addr's live current streak, 0 if it has lapsed or addr has never checked in.
