fix(misc): consolidate magic comments for rolldown

Rolldown's printer only preserves block comments containing
@__PURE__, @__NO_SIDE_EFFECTS__, or @vite-ignore. Standalone
webpackIgnore / turbopackIgnore blocks were stripped from
dist/index.mjs, leaving the surviving @vite-ignore alone and
breaking Next.js Edge / Turbopack builds. Merging all three
directives into a single @vite-ignore-bearing comment lets
rolldown keep the entire block; webpack and turbopack both scan
for their keyword anywhere in adjacent comments.
