feat.press authentication docs: product-scoped app API keys, Bearer tokens, and buyer license verification without returning PII.
Public marketplace reads and license verification do not require an API key.
Merchant-server calls use Authorization: Bearer feat_live_<key>.
Keys are product-scoped and must stay on the merchant server.
POST /api/licenses/verify with { "licenseKey": "…", "productId": "…" }.
Buyer PII is never returned.
