QF Solver 0.2.4a0

Alpha release: unified experimental nonlinear solid mechanics infrastructure.

Included scope

• J2 small-strain path on TET4, TET10, HEX8 and HEX20.
• Full Newton as the qualified nonlinear path.
• Trial/commit/rollback state handling, consistent-tangent checks and Newton diagnostics.
• Bounded external Code_Aster correlation under RQ-G08.

Explicit limits

• Modified Newton is outside production scope.
• Multi-element, cyclic, energy, cutback/retry and HEX20 profiling evidence remain outside the qualified release scope.
• No physical validation claim is made.

CI, documentation evidence and the full engineering campaign passed on the tagged commit before this release was created.
