115 deprecated the plain web /files/download endpoint (ordinary cookies no
longer get file_url), breaking 302 playback with 'no file_url'. Switch
Resolve() to the current proapi.115.com/app/chrome/downurl endpoint, which
uses 115's m115 (RSA+XOR) request/response encryption (vendored from the
MIT-licensed SheltonZhu/115driver).
115 CDN links are bound to the User-Agent used to request them, so resolve
with the playback client's own UA (plumbed from the play handler) — the host
can then issue a pure 302 the client fetches directly, preserving true offload.
