ShapeClassifier::classify($ticket) returns 'A'|'B'|'C' per policy v1:
- (severity=critical OR priority=urgent) → A
- has tag in ['security','crypto','core'] → A
- (severity=major OR priority=high) → B
- everything else → C
ProfileSelector::pickFor($ticket) walks AgentProfile::active(), matches
capability tags case-insensitively against ticket.tags:
- Class A: cheapest matching profile (cost_class alphabetic order)
- Class B: any active profile with quota_headroom_pct >= 25
- Class C: deterministic round-robin via last_dispatched_at
Pest Unit tests cover Good (matching profile picked), Bad (no match → null),
Ugly (all profiles disabled → null), plus class A/B headroom gating + class C
round-robin determinism.
