Initial commit: Layer Wizard

A GUI installer wizard for permanent rpm-ostree package layers on
bootc/image-based systems. Walks through: welcome/current-version check,
package name entry with existence check, confirmation, then a streamed
rpm-ostree install via pkexec. On success, writes a pending-confirmation
marker and installs an autostart entry so the next login shows a
"did this update work?" screen with a one-click rollback (bootc rollback
--apply) if not.

# layer_wizard
A new Flutter project.
## Getting Started
This project is a starting point for a Flutter application.
A few resources to get you started if this is your first Flutter project:
- [Learn Flutter](https://docs.flutter.dev/get-started/learn-flutter)
- [Write your first Flutter app](https://docs.flutter.dev/get-started/codelab)
- [Flutter learning resources](https://docs.flutter.dev/reference/learning-resources)
For help getting started with Flutter development, view the
[online documentation](https://docs.flutter.dev/), which offers tutorials,
samples, guidance on mobile development, and a full API reference.

# This file configures the analyzer, which statically analyzes Dart code to

# The issues identified by the analyzer are surfaced in the UI of Dart-enabled
# IDEs (https://dart.dev/tools#ides-and-editors). The analyzer can also be
# invoked from the command line by running `flutter analyze`.
# The following line activates a set of recommended lints for Flutter apps,
# packages, and plugins designed to encourage good coding practices.

linter:
# The lint rules applied to this project can be customized in the
# section below to disable rules from the `package:flutter_lints/flutter.yaml`
# included above or to enable additional rules. A list of all available lints
# and their documentation is published at https://dart.dev/lints.
#
# Instead of disabling a lint rule for the entire project in the
# section below, it can also be suppressed for a single line of code
# or a specific dart file by using the `// ignore: name_of_lint` and
# `// ignore_for_file: name_of_lint` syntax on the line or in the file

# To add assets to your application, add an assets section, like this:
# assets:
# - images/a_dot_burr.jpeg
# - images/a_dot_ham.jpeg
# An image asset can refer to one or more resolution-specific "variants", see
# https://flutter.dev/to/resolution-aware-images
# For details regarding adding assets from package dependencies, see
# https://flutter.dev/to/asset-from-package
# To add custom fonts to your application, add a fonts section here,
# in this "flutter" section. Each entry in this list should have a
# "family" key with the font family name, and a "fonts" key with a
# list giving the asset and other descriptors for the font. For
# example:
# fonts:
# - family: Schyler
# fonts:
# - asset: fonts/Schyler-Regular.ttf
# - asset: fonts/Schyler-Italic.ttf
# style: italic
# - family: Trajan Pro
# fonts:
# - asset: fonts/TrajanPro.ttf
# - asset: fonts/TrajanPro_Bold.ttf
# weight: 700
#
# For details regarding fonts from package dependencies,
# see https://flutter.dev/to/font-from-package
