Kanela Agent doesn't support Kamon 2.8.0

[ludwiggj]

With kamon (2.8.0) and the kanela agent (2.0.0), our server throws multiple
exceptions on startup. Single example:

[WARNING] 2025-12-11 14:04:04 [kanela][main] Module [Annotation
Instrumentation] doesn't have any prefixes in the 'within' setting. The
instrumentations from this module will not have any effect.
