Browsers (Firefox in particular) force-download application/rss+xml and
application/atom+xml instead of rendering them, which is confusing for
site visitors who click a feed link directly rather than pasting it into
a reader. text/xml renders inline as an XML tree in every major browser.
Feed readers (FreshRSS included) sniff the actual XML content to detect
RSS/Atom, so this has no effect on subscription behavior.

Same imio.smartweb JSON API as the Python script, but each feed regenerates
on demand (15 min file cache) instead of via cron, so it works on plain
PHP shared hosting with no server config access. Also adds facebook.php,
a caching proxy for the user's FetchRSS Atom feed so all three feeds live
under one domain and can be shared as stable URLs.
Tested with PHP 8.3 CLI: valid XML, real data (40 news, 12 events, proxied
Facebook feed).
