fix: make quickstart independently verified

[abrichr]

What changed

• Make openadapt quickstart delegate to Flow's verified tutorial.
• Run the synthetic transaction under the Standard profile.
• Confirm the saved result through the independent read-only verifier.
• Keep the recording, bundle, report, and local receipt.
• Raise the minimum Flow version to the first compatible verified-tutorial release.

Why

The former launcher quickstart used a permissive Demo replay. It could only return COMPLETED_UNVERIFIED. Flow already ships the complete verified tutorial, so the launcher should use that tested path instead of assembling a second lifecycle.

User impact

openadapt quickstart now returns success only after Flow reports VERIFIED. A halt keeps its evidence and returns a nonzero exit code. The healthy tutorial makes no model call and no Cloud call.

Checks

• 128 tests passed; 6 skipped
• Ruff passed
• Real Standard tutorial returned VERIFIED, with 2 of 2 Tier 1 effects and zero model calls
• Fault run returned HALTED_BEFORE_EFFECT, with zero model calls
• Source-boundary, lock, wheel, source archive, manifest, and diff checks passed
