v0.1.0-beta.10

Fixed

• Hardened step type guards to safely handle null/undefined/non-object values.
• Prevents runtime crash: "Cannot use 'in' operator to search for ..." in validation-message flows.
• Validation errors now render while keeping the current input step active (footer stays visible).

Validation

• Tests: 30 passed
• Build: successful (ESM/CJS + d.ts)
