Switch from conda to uv

[jpt-sn]

uv manages our dev and 2 optional dependencies.

Simply run:

• uv sync --all-extras (create a .venv and install all requirements from pyproject.toml)
• uv run -m ... (like python -m ...)

This will make easy to update dependencies:

• uv pip list --outdated (visualize outdated dependencies)
• uv sync --upgrade (upgrade all dependencies)
• uv sync --all-extras --upgrade-package accelerate==1.2.0 (update a specific library to a specific version)
• uv tree

The pyproject.toml was updated using these commands (and then manually relaxing versioning):

• uv add -r requirements.txt
• uv add -r requirements.dev.txt --dev
• uv add -r requirements.converters.txt --optional converters
• uv add -r requirements.finetune.txt --optional finetune

TODO:

• update makefile
• update ci
• update cd: uv build, uv publish
