v1.7.0

New features

• Cache pinning (#155 by @Mic92): Pin store paths in your cache so they
  survive garbage collection. The new niks3 pin CLI command keeps specific
  paths around regardless of retention policy, with full server-side support.
  See the Pinning docs.
• Configurable S3 bucket addressing style (#417 by @cterence): Choose
  between path-style and virtual-hosted-style bucket addressing via a CLI flag
  or environment variable. Fixes crash loops with S3 providers that reject
  path-style requests (HTTP 400) and that the minio-go library can't
  auto-detect.

Bug fixes

• Fix SQLITE_BUSY errors under concurrent load (#411 by @Mic92): The hook
  queue's journal_mode=WAL and busy_timeout pragmas were only applied
  to a single pooled connection. Concurrent enqueue and worker connections
  opened without them and failed immediately instead of retrying. Both
  pragmas now live in the DSN so every connection inherits them. Fixes #409.
