204 - Feature Validation

Return a structured validation report in chat that checks whether a feature's scope, scenarios, and implementation plan still agree with each other and with the actual codebase.

This is a review pass, not a redesign pass.

Output: Validation report in chat only. Do not write to .specflow/.

Required Inputs

Before proceeding, confirm:

1. Feature name
2. Validation scope — full review (default) or targeted review: cross-artifact consistency, scenario coverage, implementation simplification, or standards compliance
