* fix(cache): instrument repository cache load and save
Wrap repository cache `load()` and `save()` calls with the existing
`instrument()` helper to create OpenTelemetry spans for cache lifecycle
operations. This gives operators visibility into repository cache
performance, especially useful with S3 backends.

* fix(cache): instrument package cache init and destroy

create OpenTelemetry spans, matching the repository cache instrumentation
from the previous commit. Covers redis, sqlite, and file backends.

* Move destroy() outside init instrument span
Avoids nesting the package-cache.destroy span inside
package-cache.init, making them sibling spans instead.

* Use 'verb NounClass' span naming convention
Rename instrument span names from dot-notation (e.g.
'package-cache.init') to 'verb NounClass' pattern (e.g.
'init PackageCache') per reviewer feedback.
