🎯 Changes

Adds JSDoc (description, @param, @returns) to the exported classes, their non-private methods, and the exported arrow functions that didn't have one:

Documentation was added for ReactiveValue and watchChanges. The changes describe existing behavior and do not change runtime code.

Merge Risk: 🔵 Low · up to ff219

The watchChanges documentation may lead consumers to expect callbacks only when source results change, although tracked dependencies can trigger callbacks with identical results. This is a localized documentation issue; correct the wording before merging.

Describe the reactive trigger accurately.

A tracked dependency can change and rerun the effect even when a source returns the same value. For example, changing count from 1 to 3 can rerun a source () => count % 2. No source-result comparison gates the callback.
