Andrew Nesbitt c01f0a5c05 Fix metadata caching, 404 propagation, mirror progress, and registry stubs ... - ProxyCached now stores upstream Last-Modified in the cache and uses it (along with ETag) for conditional request handling, returning 304 when client validators match. Adds Content-Length to cached responses. - Handlers calling FetchOrCacheMetadata (pypi, composer, pub, nuget) now check for ErrUpstreamNotFound and return 404 instead of 502, matching the existing npm and cargo behavior. - Mirror jobs report live progress via a periodic callback while running, so API polls return real counts instead of zeroed progress. - Registry mirroring removed from CLI flags, API acceptance, README, and docs since every enumerator was a stub returning "not yet implemented". - Added tests for the conditional metadata path (ETag/If-None-Match, Last-Modified/If-Modified-Since, 304 responses, header omission).		2026-04-13 09:01:05 +01:00
