Add _routes.json so /, /robots.txt and /assets/* skip the worker and
don't count against the Functions request quota. rate-limit.js moves to
assets/ so the homepage reads it client-side instead of via HTMLRewriter.

- free.direct-img.link serves only unrestricted (public domain/CC0) images
from Openverse (license=cc0,pdm) and Wikimedia Commons
(haslicense:unrestricted), with optional ?src=openverse|wikimedia
- ?i=1..20 picks the i-th working image on both sites; broken links are
skipped so every index is a different image
- Openverse OAuth token is cached in KV and refreshed automatically
- Skip Flickr "photo unavailable" placeholders (served with HTTP 200)
- Free/indexed cache keys use uppercase prefixes; plain main-site keys
are unchanged so existing cache entries stay valid
- Update README, homepage, privacy policy and terms
