v2.8.0

The OCI handler had /v2/ baked into all regex patterns and Location headers.
When basePath was set to /v2 (as in stack.gallery), stripping it removed the
prefix that patterns expected, causing all OCI endpoints to 404.

Now patterns match on bare paths after basePath stripping, working correctly
regardless of the basePath value.

Also adds configurable apiPrefix to OCI upstream class (default /v2) for
registries behind reverse proxies with custom path prefixes.

 # Changelog
 
+## 2026-03-24 - 2.8.0 - feat(core,storage,oci,registry-config)
+add streaming response support and configurable registry URLs across protocols
+
+- Normalize SmartRegistry responses to ReadableStream bodies at the public API boundary and add stream helper utilities for buffers, JSON, and hashing
+- Add streaming storage accessors for OCI, npm, Maven, Cargo, Composer, PyPI, and RubyGems downloads to reduce in-memory buffering
+- Make per-protocol registryUrl configurable so CLI and integration tests can use correct host and port values
+- Refactor OCI blob uploads to persist chunks in storage during upload and clean up temporary chunk objects after completion or expiry
+- Update tests and storage integration to use the new stream-based response model and smartstorage backend
+
+## 2025-12-03 - 2.7.0 - feat(upstream)
+Add dynamic per-request upstream provider and integrate into registries
+
+- Introduce IUpstreamProvider and IUpstreamResolutionContext to resolve upstream configs per request.
+- Add StaticUpstreamProvider implementation for simple static upstream configurations.
+- Propagate dynamic upstream provider through SmartRegistry and wire into protocol handlers (npm, oci, maven, cargo, composer, pypi, rubygems).
+- Replace persistent per-protocol upstream instances with per-request resolution: registries now call provider.resolveUpstreamConfig(...) and instantiate protocol-specific Upstream when needed.
+- Add IRequestActor to core interfaces and pass actor context (userId, ip, userAgent, etc.) to upstream resolution and storage/auth hooks.
+- Update many protocol registries to accept an upstreamProvider instead of IProtocolUpstreamConfig and to attempt upstream fetches only when provider returns enabled config.
+- Add utilities and tests: test helpers to create registries with upstream provider, a tracking upstream provider helper, StaticUpstreamProvider tests and extensive upstream/provider integration tests.
+- Improve upstream interfaces and cache/fetch contexts (IUpstreamFetchContext includes actor) and add StaticUpstreamProvider class to upstream module.
+
 ## 2025-11-27 - 2.6.0 - feat(core)
 Add core registry infrastructure: storage, auth, upstream cache, and protocol handlers
