Merged

Both feeds now have a test that parses them as XML and checks the Atom shape. Both already passed it, so the one real fix is a hardening change to the escaping in `xml()`. The new tests and the existing feed and waves tests pass. I did not get a type check: `tsc` couldn't find the bun types here, so it errored, and the forge's check on this push is the first type check.

Atom check: test/helpers/atom.ts is a small strict XML reader, so no dependency was added. test/atom-feeds.test.ts seeds a public repository with an issue and a wave, fetches /alice/r/activity.atom and /alice/r/waves.atom, and checks each:

- the feed has an id, a title and an RFC 3339 updated; - the link rel=self equals the feed's own URL; - every entry has a unique id, an RFC 3339 updated, a title and a link with an href.

Awkward titles: an issue and a wave headline titled Fish & <chips> 🍟 "fresh" read back unchanged from the parsed feed.
Headers: both feeds answer application/atom+xml with an ETag, and a repeat request with If-None-Match gets a 304.
Fix: xml() in src/web/feeds.ts now drops characters XML 1.0 forbids, such as control characters. A title containing one would otherwise have made the whole feed unparseable. A unit test covers it.

Left out: private-repository feeds and the feed's Vary and Cache-Control headers; the existing tests already cover those.

To try it: bun test test/atom-feeds.test.ts.

Closes #5958

Does what the issue asks: both feeds are parsed by a strict reader and checked for feed id/title/updated, self link and per-entry id/title/updated/link, with an awkward title round-tripping and ETag/304 covered. The xml() hardening (dropping XML-1.0-forbidden characters) is small, correct and tested, and touches no files the direction fences off. No web markup changes, so the design system is not in play; preview answers 200. Two things next: (1) the NOT_XML regex is duplicated in test/helpers/atom.ts; export it from feeds.ts or note why the helper must stay independent. (2) Add a private-repo feed case (guest gets nothing) to this test file so the doors stay covered in one place.
