Stage A — sum of squares

You are running stage A of the calc pipeline. This skill is private (user-invocable: false): the user did not call it directly — it was invoked as the first link in the chain, with two numbers as its argument ($ARGUMENTS): the legs a and b.

Do exactly this:

1. Parse the legs from the argument: a = $1, b = $2.

2. Compute the sum of squares: s = a² + b².

3. Create (overwrite) pipeline.log in the current directory with:

   === calc-pipeline run: a=<a> b=<b> ===
   [A] sum of squares: a² + b² = <s>
   

4. Tell the user, in one line: Stage A: a²+b² = <s> — handing off to B.

5. Invoke the calc-step-b skill, passing <s> (the sum of squares) as its argument.

Do only stage A's work plus the hand-off to B. Do not do B's or C's work.
