M-3: PageContext.addPage minted ids from bare `page_${Date.now()}` --
two adds inside the same millisecond collided on id, so a subsequent
rename/delete/save silently acted on both pages at once. Added a
module-scoped monotonic counter combined with the timestamp
(nextPageId(), exported for direct unit testing) and used it
everywhere an addPage-style id is minted (addPage, replaceAllPages).
M-4: scopeId() lowercased + stripped non-alphanumeric characters from
the node id into a slug, so two node ids differing only by
case/punctuation (e.g. "AbC" vs "abc", or "a-b" vs "ab") collapsed
onto the same scope -- defeating the whole point of scoping ids per
node (M-1/Menu/Tabs/ColumnLayout/Gallery/etc. all rely on it). Now
hashes the raw node id via the existing djb2 stableHash() instead of
slugifying it: still deterministic (same id -> same scope) and a valid
CSS ident, but collision-resistant across case/punctuation. This
changes the exact scope strings Menu/Tabs/ColumnLayout/Gallery/etc.
emit -- expected and fine, since none of their tests pinned an exact
scope value (all already asserted structure/uniqueness).

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.
