[codex] Add QUBODrivers 0.6.1 conformance

[bernalde]

Refs #26.

Summary

• Tighten compat to QUBODrivers = "0.6.1" and QUBOTools = "0.13".
• Add the standard PySA.RandomSeed() and PySA.FinalNumberOfReads() aliases, standard num_* raw keys, and compatibility raw aliases for the legacy n_* keys.
• Seed both NumPy and Numba RNGs for reproducible PySA runs; seeded solves run the backend with parallel=false because PySA's parallel Numba kernel is not deterministic.
• Emit QUBODrivers benchmark metadata for backend, reads, seeds, status, and effective time, and declare seed, final-read, and time-limit traits.
• Update tests and README coverage for the new compat, aliases, metadata, and benchmark conformance suite.

Tests

• julia --project=. -e 'using Pkg; Pkg.test()'
  • Passed with QUBODrivers v0.6.1, QUBOTools v0.13.1, and PythonCall v0.9.35.
  • Result summaries: Package metadata 22/22, Solver attributes 21/21, README JuMP workflow 8/8, QUBODrivers 139/139.
  • Benchmark Conformance: 13/13.
• julia --project=/tmp/pysa-issue26-qubo-resolve -e 'using Pkg; Pkg.activate("/tmp/pysa-issue26-qubo-resolve"; shared=false); Pkg.add(Pkg.PackageSpec(name="QUBO", version="0.6")); Pkg.develop(path=pwd()); Pkg.status()'
  • Passed; resolved QUBO v0.6.0 with this PySA branch, QUBODrivers v0.6.1, and QUBOTools v0.13.1.

Branch Hygiene

• Base branch: main.
• Source branch point: origin/main at fccd0dd.
• Stacked status: not stacked.

• julia --project=. -e 'using Pkg; Pkg.test()': passed; Package metadata 22/22, Solver attributes 21/21, README JuMP workflow 8/8, QUBODrivers 139/139, including Benchmark Conformance 13/13.
• julia --project=/tmp/pysa-review-pr27-qubo-resolve -e 'using Pkg; Pkg.activate("/tmp/pysa-review-pr27-qubo-resolve"; shared=false); Pkg.add(Pkg.PackageSpec(name="QUBO", version="0.6")); Pkg.develop(path=pwd()); Pkg.status()': passed; resolved QUBO v0.6.0, QUBODrivers v0.6.1, and QUBOTools v0.13.1 with this checkout.
• Fresh-environment seeded solve smoke with random initialization/update: passed; repeated solves with PySA.RandomSeed() returned identical samples.
• gh pr checks 27: passed on all four CI jobs.

Merge-readiness:

• Functionally ready from this review.
