RFC: Change package managament to UV

[cjdsellers]

This RFC proposes changing the package and dependency management tooling for NautilusTrader from Poetry to UV.

Pros

• Performance (dependency resolution, env setup, package installation, etc)
• Improved/simplified environment setup
• Improved/simplified python version management (could also replace the recommended pyenv for this?)
• Potentially better design principles than Poetry - less issues, more longevity?
• Gaining community adoption fast

Cons

I'm not currently aware of any disadvantages of using UV over Poetry?

Questions

• Is there anything which Poetry can do right now which UV can't, specific to NautilusTrader?
• Does anyone have any hesitations about making this change soon?
• Does anyone have suggestions for alternatives? (e.g., pixi already suggested and is conda specific)
