add-featurelisted

Add a new conforming vertical-slice feature (Screen + ViewModel + UseCase + Repository + spec + tests + golden tree + nav route + DI wiring) to this Compose Multiplatform app, cloned deterministically from the project's configured exemplar feature (qa/approvals.json's exemplarFeature — `home` by default). Use this when the user wants to "add a feature", "add a screen with data", "scaffold a feature", "create a new screen backed by a repository", "add a list screen", or names a new domain noun they want a screen for (e.g. "add a Favorites feature", "I need a Bookmarks screen"). Works with NO create-cmp plugin installed — the stamper (`qa/scaffold-feature.mjs`) and this skill both ship inside the generated project.

This is the same resolution the approvals registry uses for the governed `exemplar-feature` artifact, so what gets stamped is always exactly what the human signed off on. After the genesis walk retargets `exemplarFeature` to the user's own first feature, every stamp from then on clones *their* pattern in *their* domain language — do not assume `home` still exists as the exemplar; read the config (or just run the stamper: it resolves the source itself). If the configured exemplar has grown files beyond the canonical 11-file shape (an extra ViewModel, a helper, a second use case named for its entity), the stamper clones **only the canonical set** and prints a `WARNING:` listing exactly what it skipped — never silently. When you see that warning, tell the human: the extras are part of the exemplar's pattern in spirit but
