feat(adapter): Lit component scaffold + drift report (WHYNOT-WP-0002 T07) Extend make adapt-lit beyond tokens: parse src/elements/.js, compare each IR component contract against its <wn-> element, and emit per-component drift reports + a machine roll-up (adapters/lit/drift/), with write-once stubs (adapters/lit/stubs/) for genuinely new components. Never overwrites hand-authored sources. - Severity split: actionable drift (prop-missing, attribute-mismatch, variant-axis-missing, tag-mismatch) gates with exit 3; non-portable + prop-extra are informational (the IR carries React style/onClick; Lit is richer than the minimal designbook) and don't gate. - Current state: 7 ok, 3 actionable drift for human triage — PipelineStrip (wn-pipeline-strip vs hand-authored wn-pipeline rename), PageHeader (actions is a slot, not a prop), Sidebar (IR 'current' axis absent on the element). - _report.json reuses generatedAt/irRef when drift is unchanged (no git churn).
