[Feature Request] Specify path for .fvm directory

[supposedlysam-bb]

Problem Statement

Is your feature request related to a problem? Please describe.
In version 2 and in version 3 of fvm I've experienced issues where CLI tools and the VSCode debugger itself will act on the flutter code through the .fvm directory.

For instance: when debugging my Flutter project in VSCode with "Debug My Code" on and "All Exceptions" checked, it will still show me errors inside of the flutter code. Note: I DO NOT have "Debug My Code + Packages + SDK" turned on.

I've also experienced issues with recursive features of CLI tools including the very_good_cli.

Proposed Solution

Describe the solution you'd like
I'd love to have an option in the .fvmrc file to add a path (relative or absolute) for the .fvm directory so I can specify that it lives somewhere outside of my project.

.fvmrc with directory path

{
  "flutter": "3.19.3",
  "fvmPath": ".."
}

With the addition of this change I could move my project into another folder and have the .fvm directory live there.

Prior to Change

.
├── my_project

After the Change

.
├── my_project_workspace
│   ├── .fvm
│   ├── my_project

Considerations

Describe alternatives you've considered
I've considered reaching out to the maintainers of each tool I use and report the problem, but if I were able to move the location of the .fvm folder so it's outside of my project I wouldn't need to do this in the future.
