Image posts wrap the post date in an <a> permalink
(<div class="post-date"><a href="/posts/ID">DATE</a></div>); text-only posts
don't. Our hand-written <div class="post-date">([^<]+)</div> regex matched ONLY
the unwrapped case, so every image post got a null published_at and sorted to the
top of the feed looking broken (cheunart 2026-06-17). Port gallery-dl's
_data_from_post method: text up to the first </, then after the last > — handles
both. Verified against the live raw feed (all 6 dates now parse).
Robust logging (operator request): _parse_posts now logs per-page parse stats
(posts / dated / with-body) and a WARNING canary when posts parse but NONE get a
date or body while the raw markers are present — i.e. our extraction diverged
from the live markup. Makes this failure class diagnosable from the worker log
alone, no authed re-fetch needed.
Test: a permalink-wrapped date parses to ISO.
