Change log for hatter

Version 0.2.0

Breaking changes

• Platform-specific types are no longer re-exported from Hatter. Import them from their own modules instead: Hatter.Permission, Hatter.SecureStorage, Hatter.Ble, Hatter.Dialog, Hatter.Location, Hatter.AuthSession, Hatter.Camera, Hatter.BottomSheet, Hatter.Http, Hatter.NetworkStatus, Hatter.Locale, Hatter.I18n, Hatter.FilesDir.
• AppContext, derefAppContext, freeAppContext, and newAppContext moved to Hatter.AppContext (no longer re-exported from Hatter).
• newMobileContext and freeMobileContext are no longer re-exported from Hatter (available from Hatter.Lifecycle).
• FFI dispatch functions (haskellOnPermissionResult, haskellOnBleScanResult, etc.) are no longer in the Haskell export list. They remain available as C symbols via foreign export ccall.
• Removed haskellGreet (dead hello-world smoke test, unused by any app code).

Added

• Hatter module now has a haddock header with overview, usage example, and a directory of platform subsystem modules.
• Export list organised under haddock section headers: App setup, Widget, Actions, Animation, Lifecycle, Error handling, Internal.
• Full Hatter.Widget re-exports in the main module: WidgetStyle, defaultStyle, Color, colorFromText, colorToHex, ImageConfig, ImageSource, ResourceName, ScaleType, TextAlignment, TextInputConfig, InputType, WebViewConfig, MapViewConfig, button, text.
