Subject: [PATCH] fix: valid feed.xml entity handling, repoint python-lectures
 redirect

Two pre-existing bugs found while verifying the GitHub Actions deploy
migration (#199):

- feed.xml truncated post content *after* escaping it, slicing XML
  entities like &quot; in half and producing an invalid feed. Reorder
  to strip_html | truncate | escape so truncation happens on plain
  text and escaping is applied last.

- /python-lectures/ redirected to /projects/#filter=lecture, a page
  that has never existed (404). Point it at /lectures/, where the
  lecture series are listed today.
