fix(core): prevent lazy-resolver double-processing on Freedium reader images

Browse source 
_archivrResolveLazyImgs is called twice: before Readability (_pre) and
after the post-body stamp pass (_post). The stamp pass sets data-archivr-src
but previously left data-src/data-zoom-src/etc intact, so _post's
'lazySrc && _isPlaceholder' condition fired on the same images and
rewrote src to the CDN URL — which SingleFile then tried and failed to
fetch from the Freedium proxy context, redundantly.

Fix: strip all lazy attrs (data-src, data-lazy-src, data-zoom-src,
data-original, data-lazy) when stamping data-archivr-src. _post then
finds no lazySrc on those images and skips them cleanly. Rust owns
them via data-archivr-src. _post continues to handle any remaining
placeholder images not covered by the stamp pass (non-Freedium reader
captures).
