Uses cache-tag definitions from the matched endpoint (already available
on ctx.items.__endpoint_meta.cacheTags) to compute deterministic cache
keys from request data (params, query, body, headers).
GET: Computes cache key → serves cached response if valid →
handler never executes. On cache miss, runs the handler and caches
the response.
Mutation (POST/PUT/PATCH/DELETE): Lets the handler run, then
invalidates all cache entries whose tag names start with any of the
endpoint's cache tag names. Older in-flight reads cannot refill them.
By default, retain at most 1000 keys and bodies up to 65,536 bytes. Private/no-store and
Set-Cookie responses are not cached. Install after authorization and encode
every identity/tenant/representation dimension in tag properties.
Server-side cache response middleware.
