Detailed Description

CDN edge-cache tier - pure engine (PC_ENABLE_EDGE_CACHE).

The caching reverse-proxy edge that services/web/httpcache is the origin-side groundwork for. This header is the pure, host-testable core: the response header-field access and HTTP-date math that httpcache lacks, RFC 9111 freshness (lifetime + age), and the deterministic cache key + SHA-256 digest + Vary secondary key. No sockets, no PC, no heap - the socket glue (edge_cache_proxy) and the L2 SD tier (edge_cache_sd) layer on top.
