feat: add mid-circuit measurement, feed-forward, and qubit reset#4
Conversation
Enable dynamic quantum circuits with projective measurement, classical conditioning, and reset in both statevector and density matrix simulators. - gate.Reset shared pseudo-gate singleton - ir.Condition gains Clbit field for simulator-authoritative bit index - ir.IsDynamic() detects mid-circuit measurement/conditions/reset - Builder: Reset(), If(), IfBlock() methods - Statevector RunDynamic: per-shot sim with stride-based collapse - Density matrix RunDynamic: per-shot sim with noise channel support - Run() auto-dispatches via IsDynamic(), preserving fast path - QASM parser resolves Condition.Clbit from register+index - QASM emitter handles new Condition format - Draw: reset "|0>" label, "c:" prefix for conditioned ops - Transpile: condition propagation through decomposition, cancel/merge respect measurement/reset boundaries - Stats: Measurements, Resets, ConditionalGates, Dynamic fields - Tests: teleportation, conditional, reset+reuse, IsDynamic (14 new)
