@harperfast/prerender v0.3.4

Follow-up to the v0.3.3 cache-key normalization (PR #14 review):

• Redirect target is now re-sorted + encoding-standardized (normalizeUrl(…, ['*'])) before building its cache key, so a redirected render lands on the key serving looks up (it was decode-only before).
• cacheKeyUrl returns '' for falsy input instead of a "null"/"undefined" key.
