Function adjust_weights 

pub fn adjust_weights(
    base: &ScoringConfig,
    compaction_count: Option<i64>,
) -> ScoringConfig

Return a ScoringConfig with category weights redistributed according to the compaction-level priority table.

For count <= 1, weights are left unchanged. For count == 2 and count >= 3, existing category weights from base are sorted descending and reassigned by priority order:

• Count 2: Reinforcing > Corrective > Stateful > Decisive
• Count 3+: Reinforcing > Stateful > Corrective > Decisive

uncategorized_weight and importance_half_life_secs are preserved from base.
