vmec-jax v0.0.18

Highlights

• Retuned the public QA/QH/QP optimization accepted/trial VMEC budgets to reduce default optimization wall time while keeping stricter audit settings documented.
• Preserved compact inactive asymmetric scan velocity state when resuming old fixed-boundary scan payloads, avoiding unnecessary graph and memory expansion.
• Added bounded QI budget-smoke provenance to the research-grade performance/differentiability plan.

Validation

• Ruff and diff checks passed locally for the release bump.
• Focused optimization/scan tests and Sphinx docs passed on the preceding code commits.
• GitHub CI is expected to publish to PyPI from this release.
