rns browser, standalone site server, unified add form

- /rns/<hash>/<path> proxies pages over RNS with link rewriting - fetch_remote_page() in rns_client.py for generic RNS page fetching - mesh_sites table for persisting saved hashes - standalone site_server.py with its own RNS identity - tinyweb-site/index.html: SPA with RSS-aware nav (/rns/<hash>/ prefix) - unified /add form: single input accepts URL or 32-char RNS hash - RNS add indexes into pages table (fetch root page, extract title/desc) - rns:<hash> URLs displayed in browse/search, linked to /rns/<hash>/ - expand RNS whitelist: allow GET /, /about, /pages, /tags, /share
