Manage local dependencies (`~/.psdk-cli/pokemonsdk`, `GameDataPacks`, etc.)

[AerunDev]

Description

As the CLI, I need to maintain my own repositories and dependencies in ~/.psdk-cli to operate independently from local PSDK projects.

Acceptance criteria

• Dependencies are cloned into ~/.psdk-cli.
• The CLI works standalone when no project is found.
• Local versions can be updated automatically or manually.

This task may also be result of other commands, we keep it to check afterward that all the commands do behave as expected in that regard
