Unified run command

[T-256]

Summary

As we going forward, uv run and uv tool run commands are getting more similar to each other, opened this to discuss about blockers of unified run command which could be smart (and environment aware) command that also accepts opt-in/opt-out arguments to focus on what user needs.

Prior discussions:

• allow "uv run" to work without a project #8666
• Should uvx use a project dependency if available? #7186
