Introduce benchmarks using a large (~117KB) GraphQL query to measure parse and pickle serialization performance. These provide a baseline for comparing serialization approaches in subsequent commits. Baseline performance (measrued on a Macbook Pro M4 Max): - Parse: 81ms - Pickle encode: 24ms - Pickle decode: 42ms - Roundtrip: 71ms
Prepares AST for immutability by using tuples instead of lists for collection fields. This aligns with the JavaScript GraphQL library which uses readonly arrays, and enables future frozen datastructures.

Note: It looks like you can't easily make stacked PRs in an open source repo you do not have write access to, since the merge base does not exist in the remote.
