- Deleted `@kit/baselime` package and its related files.
- Removed Baselime service registration from monitoring in API services.
- Cleared `registerInstrumentation`, hooks, provider components, and server utilities associated with Baselime.
- Updated package dependencies to exclude `@kit/baselime`.
