fix: Use Vue 3 function refs for child field components (#13)

- Replace dynamic string refs with function refs for Vue 3 compatibility
- Add fieldRefs data property to store child component references
- Add setFieldRef() method to collect refs from function ref callbacks
- Update fill() method to use fieldRefs object for accessing child components
- Add cleanup for fieldRefs in beforeUnmount lifecycle hook

The previous fix using :ref="'field-' + attribute" didn't work reliably
in Vue 3's v-for loops. Function refs provide direct access to components.

+## [1.0.14] - 2025-11-25
+
+### Fixed
+- Fixed dependent field values not being saved on form submission (Vue 3 ref pattern)
+- The previous fix in v1.0.13 used dynamic string refs which don't work reliably in Vue 3 v-for loops
+
+### Changed
+- Switched from dynamic string refs (`:ref="'field-' + field.attribute"`) to Vue 3 function refs (`:ref="(el) => setFieldRef(field.attribute, el)"`)
+- Added `fieldRefs` data property to store child field component references
+- Added `setFieldRef()` method to properly collect and manage child component refs
+- Updated `fill()` method to use the new `fieldRefs` object for accessing child components
+- Added cleanup for `fieldRefs` in `beforeUnmount` lifecycle hook
+
+### Technical
+- Vue 3 requires function refs when using dynamic ref names in v-for loops
+- Dynamic string refs like `:ref="'field-' + x"` create arrays but are unreliable to access via `$refs[key]`
+- Function refs `:ref="(el) => refs[key] = el"` provide direct access to component instances
