The handler stores NuGet ids lowercased, but purl keeps nuget names as written, so package rules get lowercased before they're matched. Case in a rule doesn't matter.
The mirror stores ids as given, so a mixed-case PURL ends up as a copy clients never get. Until that's fixed, the docs ask for lowercase ids in mirror lists.

Every built-in ecosystem upstream can now be set via the upstream
config block or PROXY_UPSTREAM_* env vars, with allow_private_hosts
and allow_loopback controlling access to non-public addresses.
- Bump github.com/git-pkgs/registries to v0.6.0: the fetcher now
honours HTTP_PROXY, gates dialled IPs against the safehttp block
list, and Version.Integrity is populated for pub, julia and nuget
- Replace internal/cooldown with github.com/git-pkgs/cooldown v0.1.1
(identical surface, lifted from this repo)
- Update docs/architecture.md to point at the external package
Add a `proxy mirror` CLI command and `/api/mirror` API endpoints that
pre-populate the cache from various input sources: individual PURLs,
SBOM files (CycloneDX and SPDX), or full registry enumeration.
The mirror reuses the existing handler.Proxy.GetOrFetchArtifact()
pipeline so cached artifacts are identical to those fetched on demand.
A bounded worker pool controls download parallelism.
Metadata caching is opt-in via `cache_metadata: true` in config (or
PROXY_CACHE_METADATA=true). The mirror command always enables it. When
enabled, upstream metadata responses are stored for offline fallback
with ETag-based conditional revalidation.
New internal/mirror package with Source interface, PURLSource,
SBOMSource, RegistrySource, and async JobStore. New metadata_cache
database table for offline metadata serving.
* Add cooldown support for NuGet
Filter versions from NuGet registration pages based on the
catalogEntry.published timestamp. Handles both RFC3339 and NuGet's
fractional-second timestamp formats. When cooldown is disabled,
registration requests are proxied directly without parsing.
* Update README table to mark NuGet cooldown support
