* Implement IME composition handling in WasmWebBrowser
This update introduces support for handling Input Method Editor (IME) composition events in the WasmWebBrowser class. The changes include:
- Added event listeners for `compositionstart`, `compositionupdate`, and `compositionend` to manage the composition state and data.
- Skipped normal input events during composition to prevent interference.
- Sent the final IME input result to the WebAssembly module upon composition end, ensuring proper handling of user input.
These enhancements improve the text input experience for users utilizing IME, particularly for languages requiring composition.
* chore: remove log
This allows an app dev/user to create and populate a new widget
within the PageFlip parent widget *before* waiting for it to be drawn.
Previously, the child widgets within PageFlip were either created
upon app load (which is inefficient) or upon draw (which is too late).
* Refactor stack navigation into a proper stack
- Replace show_stack_view_by_id with push/pop/popToRoot methods
- Add proper navigation stack with history tracking
- Fix animation transitions between consecutive views
- Add stack inspection methods (depth, can_pop, current_view)
- Maintain backward compatibility with deprecated methods
- Update action enum to use Push/Pop/PopToRoot variants
* Add support for multiple instances of StackNavigation.
- Introduced full-screen flag necessary to disable full-screen positioning and sliding animations when needed.
