Provide an easy way to rename projects in Qt Design Studio

Description:

Currently, once a project is created in Qt Design Studio, renaming the project is a tedious and error-prone process.

For example, if a user creates a project named "QQControlCustom", this name gets propagated to multiple locations:

• The root folder name

• The .qmlproject file name

• The .qmlproject internal content

• Generated resource or asset paths

• Possibly even inside component or file names depending on the templates used

To rename the project, the user must manually:

1. Rename the project folder

1. Rename the .qmlproject file

1. Edit the contents of that file

1. Manually verify and fix any other name dependencies across the project

This is cumbersome, especially for beginners or designers using Qt Design Studio.

Proposal:

We propose adding a "Rename Project" option to the context menu when right-clicking a project in the Projects view. This feature would:

• Prompt the user to enter a new project name

• Automatically update all relevant names and paths throughout the project

• Maintain project integrity without requiring the user to manually edit files or restructure folders

Impact:

This improvement would:

• Significantly enhance usability and user experience

• Save time and reduce user errors during early prototyping or when rebranding projects

• Make Qt Design Studio feel more polished and aligned with user expectations from modern IDEs

It is especially valuable for designers or non-technical users, who may be less comfortable manually editing project files and paths.
