Running `uv sync` fails. Can't find Rust compiler when trying to install tiktoken.

[quiaro]

I downloaded the latest from the repo and tried setting it up using uv.
When I ran uv sync, I got an error related to the tiktoken package.
In the stack trace, I found: error: can't find Rust compiler.

FIX:

• Downloaded and installed Rust per https://www.rust-lang.org/tools/install (mac install):

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

• Refreshed the shell session
• Ran uv sync again.

The tiktoken package was built and installed successfully.
