slugify('!!!') stripped down to '' since punctuation-only names have no
a-z0-9 characters left; buildSavePayload then wrote filename = '' +
'.html'. slugify now falls back to 'page' when the computed slug is
empty, so uniqueSlug's existing dedupe (page, page-2, ...) applies same
as any other collision. Landing page slug stays forced to 'index'.

Two pages that slugify to the same string (e.g. both named "About")
previously both published to about.html, silently overwriting each
other on publish. Add a pure uniqueSlug(base, existingSlugs) helper
that appends -2, -3, ... on collision, and apply it in addPage,
renamePage, and replaceAllPages. The landing page's slug stays locked
to 'index' regardless of collisions, matching existing behavior.
