- generatePlan computes a histCount Map once; scoreCandidate now does an O(1)
lookup instead of filtering the whole history per candidate per day.
- minGap eligibility finds the latest prior date in a single pass instead of
spreading history+monthAssignments into a new array and sorting it.
Behaviour is unchanged (all algorithm tests pass).

generatePlan gains a preAssigned parameter: manual entries occupy slots,
count toward eligibility (maxPerMonth/minGap) and are never double-booked;
only the remaining slots per day are auto-filled. The generate handler now
keeps manual:true entries for the month instead of wiping them.
Adds tests for slot occupation, fully-manual days, and maxPerMonth counting.
