files: /me and /public are two separate per-user areas

Per feedback: /me is PRIVATE and the public folder must be its own top-level area, not nested under /me. - A member now has two sibling areas over SFTP: /me (private, <root>/files/users/<name>) and /public (their own public files, <root>/files/public/<name>), served anonymously at ~<name>/public. - Drop the global shared /public web route and the /me/public nesting. The anon surface only exposes ~name/public; /me has no anon route. - Both owned areas count toward the quota gauge. - Index publish hint, docs, and setup.sh updated to scp :/public/. files.<host> stays a file server; member sites remain on the BBS.
