**Description**
Currently hooks lacks proper analytics support.

**Proposed solution**
Add configurable analytics with sensible defaults.

**Priority**: Low/Medium

Start by locating the hooks, handlers, and analytics entry points mentioned in the issue. Clarify how TypeScript types relate to configurable analytics and its sensible defaults before changing anything. Done means the intended analytics behavior and handler types are defined and verified against the project’s existing checks.
