chore(napi): bump @firecrawl/pdf-inspector to 1.10.4 (#147)

Ships #145: exclusive item->region assignment in extract_text_in_regions
(overlapping layout regions no longer double-extract shared items —
duplicated lines on 21% of a 2,078-doc bench corpus, with occasional
content loss when downstream dedup kept the wrong variant).
