fix: keyboard layout mapping causing shortcut malfunction

Keyboard layout libraries using dynamic import were not included in bundle,
causing runtime module resolution errors

- Restored keyboard-layout-converter.ts to static import to resolve bundling issues
- Removed async/await and converted to synchronous functions (generateKeyVariants, findMatchingShortcut)
- Restored convert-layout.d.ts type definition file
- Rolled back performance optimization while preserving Strategy Pattern

fix #143
