[na] Score time and error-budget with cost weights Refs #484 - #539

Conversation
The placeholder time objective and error-budget mode both read the target cost_model. A stage-weight change, with the other weights held fixed, flips a verified schedule, and each verified total is lower under the weights that chose it. qaoa_graph.qn still verifies; its resource report matches that schedule.

The time objective scores with the target cost_model, so the verified repetition and surface hybrid schedules change. Their resource-report snapshots match those schedules. Routing-aware search on the cubic stats fixture completes five layers. Refs #484 Co-authored-by: Arnab Ghosh <ag2583@cornell.edu>
Time and error-budget scoring with the target cost_model verifies repetition_d3_memory.qn at 52 cycles. The two disjoint CNOTs in parallel_gates_na_mlir.qn each take their own Rydberg stage; the FileCheck pins match that schedule. Refs #484 Co-authored-by: Arnab Ghosh <ag2583@cornell.edu>
QASM and QN preflight both verify at 82 Entangle2 gates and 7 Rydberg stages. Routing-aware still schedules the four circuit layers. The RAP routing comparison stays inside its existing tolerances. Refs #484 Co-authored-by: Arnab Ghosh <ag2583@cornell.edu>

The placeholder time objective and error-budget mode both score placement with the target
cost_modelweights, including the checked-in placeholder vector. Error-budget mode still fails closed when the target has noerror_model.A test holds movement, transfer, and idle fixed and shows the stage weight flip a verified schedule through both objectives. Each verified total is lower under the weights that chose it.
test/na/qaoa_graph.qnstill verifies. The zoned resource-report golden matches that schedule: 12 Rydberg stages, 1805 µs of rearrangement, 3693 µs total.Refs #484
