Use quotes in zsh macos '.[torch]' or ".[flax]" when using uv pip install

[sparshrestha]

On macOS zsh terminal, extra syntax like .[torch] is interpreted as a glob pattern unless quoted. This causes installation to fail with:

zsh: no matches found: .[torch]

Solution: Quote the extras specifier like this '.[torch]' or ".[flax]"

uv pip install -e '.[torch]'
uv pip install -e ".[flax]"
