chore: update project configuration and dependencies

* Add .fvmrc file to specify Flutter version 3.29.3 for consistent development environment.
* Update Dart SDK constraints in pubspec.yaml to allow versions from 3.3.0 to less than 4.0.0.
* Modify pubspec.lock to reflect Dart SDK version change.
* Enhance VSCode launch configurations for improved development experience with new options for running with webdev.
* Introduce settings.json and tasks.json for better integration with VSCode, including a task for webdev serve with auto-refresh capability.
