Resolve a link by slug

Looks up a link by its slug and optional domain. Returns the link's deep link configuration for SDK use. A resolve that returns link data to the WarpLink SDK on a device records one click with the source app_open, so an in-app open appears in analytics and counts toward your plan's click allowance. Nothing else records a click: not a refusal, not a known bot, and not a server script or CI job calling this endpoint with a standard API key, which still receives the link data. destination_url and the platform URLs are normalized exactly the way the redirect path normalizes them, so a bare origin comes back with its trailing slash, and custom_params includes the query parameters already on the stored destination. A resolve that carries the same X-WarpLink-Tap-Id as an earlier one records one click, not two, so a client may safely retry a request whose response it never received. A slug that is the old address of a moved link resolves to the moved link: the response carries the link's current domain and slug, and the old address keeps working for as long as the link exists.
