Subject: [PATCH 01/11] Add useOnFormValueChange hook with Storybook examples

- Created useOnFormValueChange hook for reactive form behaviors
- Hook watches specific fields and executes callbacks on value changes
- Added comprehensive Storybook story with 3 examples:
  - Cascading dropdowns (country -> state selection)
  - Auto-calculation (order totals with discount)
  - Conditional fields (show/hide based on selection)
- Includes full TypeScript types and JSDoc documentation
- Added interactive tests for all story examples

+/**
+ * # useOnFormValueChange Hook
+ *
+ * A hook that watches a specific form field and executes a callback when its value changes.
+ * This is particularly useful for creating reactive form behaviors where one field's value
+ * affects another field.
+ *
+ * ## Key Features
+ * - **Reactive Forms**: Make fields respond to changes in other fields
+ * - **Conditional Logic**: Show/hide or enable/disable fields based on other values
+ * - **Auto-calculations**: Automatically calculate derived values
+ * - **Data Synchronization**: Keep multiple fields in sync
+ *
+ * ## Common Use Cases
+ * - Cascading dropdowns (country → state → city)
+ * - Conditional field visibility
+ * - Auto-calculating totals or subtotals
+ * - Applying discounts based on order value
+ * - Formatting or transforming values

Subject: [PATCH 02/11] Fix useOnFormValueChange hook null handling and update
 stories

- Make useOnFormValueChange hook more defensive by checking for null formMethods
- Add loading checks to story components to prevent null handleSubmit errors
- Switch from fetcher.Form to regular form elements in stories
- Hook now gracefully handles cases where form context is not available
