prerender-v0.7.0 — @harperfast/prerender

One canonical cache-key normalization across the whole render flow (PR #28).

• Single canonicalizeUrl replaces normalizeUrl+cacheKeyUrl; raw-query preserving (no more +/%20 collapse), applied at every key site (ingress, bot-read, sitemap, discovery, redirect re-key).
• Fixes permanent cache miss on multi-word-facet pages, wrong-facet origin proxy on miss, and spurious redirect-driven RenderTarget deletion.
• Encodes the reserved | in the url-half; sitemap skips malformed <loc>.

Pairs with @harperfast/prerender-browser v1.11.0. Behavior pinned by test-vectors/canonicalize-url.json.
