v3.0.0

Major release adopting Frost UI 4 and fQuery 5, adding compiled ESM exports, and improving switch accessibility, transitions, form synchronization, and component cleanup.

Breaking Changes

• Requires @fr0st/ui 4 and @fr0st/query 5 as peer dependencies. Browser applications must load compatible builds; Frost UI's all-in-one bundle supplies both dependencies. Load Frost UI 4 CSS alongside the Switch stylesheet.
• The package root now resolves to the compiled ESM bundle. Package exports expose the root, dist/*, and src/*; internal prototype modules have been replaced with private component methods.
• Declared Node.js support is ^20.19.0 || ^22.13.0 || >=24.

Fixed

• Exposed a single accessible switch by hiding the original checkbox from the accessibility tree while retaining native form submission and required validation. Preserved focus when initializing a focused input and restored its original aria-hidden value during disposal.
• Improved accessible names from explicit labels, wrapping labels, and existing ARIA label references, and preserved existing or application-modified label IDs during cleanup.
• Handled rapid and interrupted state transitions, allowed repeated toggles to reverse the pending target, and prevented stale animation callbacks from changing reset or disposed controls.
• Synchronized the rendered state after native form resets, respected canceled resets and subsequent explicit state changes, and supported inputs associated with external forms.
• Recovered automatic sizing after hidden initialization and fell back to measured widths for invalid width options.
• Canceled active dragging when disabling a switch, suppressed drag-generated clicks, and corrected RTL positioning and drag direction.
• Restored original input visibility and tabindex while preserving unrelated classes, and made repeated disposal safe without affecting replacement instances.
• Removed the demo intro's column divider and corrected its Frost UI version badge.

Improved

• Replaced JavaScript-driven movement with CSS transform transitions, scaled transition duration for partial movement, and respected reduced-motion preferences.
• Updated rendering and demos for Frost UI 4, including semantic styles, five sizes, themes, and RTL layouts.
• Added compiled ESM and UMD bundles with source maps, modernized build tooling, and updated development dependencies.
• Added cross-browser Playwright coverage and CI, including accessibility, focus, form validation, reset, hidden-layout, transition, and disposal regression tests.
• Aligned README installation and development guidance and improved JSDoc option types and state-change documentation.
