@harperfast/prerender 0.97.3

A URL too long to be a cache key is proxied to the origin, not answered 500 (#230).

• Harper refuses a primary key over 1978 encoded bytes, and the first table read on the bot serve path threw on it, so the crawler got a 500 for a URL the origin serves.
• CacheKey.fitsKeyLimit(url) is checked where a URL enters: a bot request over the limit is proxied and nothing else (bot_serve bypass, origin_fetch reason key-too-long, one warn); a sitemap <loc> over it is invalid; a render redirecting to one discards the render and keeps the target (a 301 retires the source and adopts nothing, unkeyable-destination); the admin explain and revalidate answer without reading.

No schema or config change: a worker restart loads it.
