v0.10.0 — deploy a frontend from ChatGPT

Added

• deploy_frontend takes the site in one of three ways instead of only a local folder: files (inline path + content, base64 for binaries; up to 500 files / 8MB) so ChatGPT and every hosted client can write a page and put it live in the same turn; zipUrl (a public https zip such as a Lovable/Bolt export or a GitHub release asset, up to 50MB; a single top-level folder is re-rooted); and dir as before. Exactly one is required. Private hosts, plain http and non-zip answers are refused before anything is uploaded.
