chore(fmt): format optimized_libs after #8337

[proggeramlug]

Summary

#8337 landed from a fork branch whose cargo fmt --all -- --check was failing on
crates/perry/src/commands/compile/optimized_libs/no_auto.rs (lines 5, 89, 98, 134,
154) and optimized_libs/tests.rs:1299. I could not push to the fork, so this
applies the formatting immediately after the merge rather than bouncing an
otherwise-green PR over whitespace.

Attribution checked before merging #8337: clean main was fmt-clean (exit 0),
and #8337 alone on current main still failed — including no_auto.rs, which
the #8338 merge never touched. So it was the branch, not the auto-merge.

Validation

• cargo fmt --all then cargo fmt --all -- --check — exit 0
• Only the two files above changed

Summary by CodeRabbit

• Chores
  • Applied code formatting updates to compilation and WebAssembly testing components.
