Fixing subtle bug: lstrip removes all matching characters, including potentially required ones. Use removeprefix instead.

harden eval: prevent the calc tool from accessing globals and locals
...
By passing empty globals() and locals() to eval() we can prevent simple
malicious cases where the user gets the model to output something like
```<global variable/func> or "a".count("a")```
e.g.
```signal.raise_signal(9) or "a".count("a")``` which would kill the process.
or one could maybe get it to output secrets etc.
I think to make it 100% secure one would need to parse the AST and only execute secure nodes but this should make it much more robust.

add the SpellingBee task so that nanochat can count r in strawberry etc. along the way we had to add a bunch of new functionality, e.g. extend the calculator to support the count function of python. possibly the current TaskMixture uses way too many synthetic examples of SpellingBee because the eval gives us exactly 100% performance on spelling. We can tune this later to reclaim some wall clock time here I think
