Case contract

Worked segments [start, end] of one workday (unordered, possibly overlapping) and a minimum wage in cents. Overlapping or touching segments merge. Spread is last end minus first start. Each gap longer than 60 minutes is a split. A spread over 600 minutes earns one hour of minimum wage and replaces any split premium; otherwise each split earns min_wage // 2, for at most two splits. Return [spread, splits, premium].

Why this case matters

Spread-of-hours and split-shift premiums are frequent roster-pay rules that depend on correct interval handling.
