fix: extract title from h1 or URL slug when page title starts with #

When readallcomics.com pages have a <title> containing only the issue
number (e.g. '#018 (2026)'), fall back to the h1 element first, then
derive the title from the URL slug by stripping the trailing year and
title-casing the hyphen-separated segments.

Closes #4
