Changelog

Unreleased

• Add the :azure-blob konserve backend.
• Support Azure Identity, connection strings, explicit credentials, and injected service clients.
• Add ETag/If-Match optimistic locking with HTTP 412 conflict handling.
• Add local and CircleCI integration tests against Azurite 3.36.0.
• Align git-derived versions and GitHub releases with the konserve cloud adapters.
• Stream binary values and internal blob copies instead of buffering complete blobs in memory.
• Validate metadata and EDN component lengths before allocation, with configurable size limits.
• Bound the shared Azure client cache and blocking-I/O executor, and report executor saturation to callers.
• Await asynchronous streaming callbacks, realize paged listings on the I/O executor, and avoid retaining stale ETags or payloads in exception data.
