Post-patch validation

Uses a uv-driven Python runner and isolated Git worktrees to validate a structured plan, preserve logs, and distinguish findings from evidence gaps. It runs local code with the caller's privileges, rejects remote or production targets, requires execution authorization, and still leaves acceptance to human review.
