Add CSE logical tree fuzz test

[prozacchiwawa]

Summary

• Add a deterministic CSE fuzz test that generates logical tree specifications with Scalar and Condition entries.
• Render guarded Chialisp retrieval programs with randomized if/let/let*/assign wrapper stacks up to depth 6.
• Construct matching argument trees from satisfied specs and assert compiled program output matches the generated specification.
• Define a local lazy and macro for the generated programs so prerequisite guards can be rendered as requested.
• Keep generated program sizes and default iteration count bounded while preserving depth-6 wrapper stacks.

Testing

• cargo test test_cse_logical_tree_fuzz -- --nocapture
