 * Selection (priority order = `claudeAlwaysImport` profiles first, then the rest in given order):
 * (1) `claudeAlwaysImport` profiles (developer, ta) are considered FIRST — they remain the priority primary roles when selected.
 * (2) Profiles are admitted in priority order until the next one would exceed the budget, then selection stops — a prefix of the priority order. We never skip an over-budget profile to admit a later smaller one, which would surprise the user with an out-of-order always-load set.
 * (3) At least ONE profile is always-loaded whenever any profile is selected, so the main agent always has a role profile in context — even if the first profile alone exceeds the budget (better in-context than the agent blind to its own role).
 *
 * Everything not selected for always-load is returned as `onDemand`.
