💡 What:
Removed unnecessary Vec allocations in xdk-build/src/python.rs during output parsing from the custom Python formatter script. Replaced string-based .split("\n") with character-based .split('\n') and bypassed intermediate Vec collections by iterating directly and matching on parts.next().

🎯 Why:
The previous implementation performed multiple O(N) heap allocations on the critical formatting logging path (collecting all lines into a Vec, and then collecting all space-separated parts of each line into another Vec).

📊 Impact:
Eliminates intermediate runtime memory allocations for string parsing entirely in this block, significantly reducing memory pressure and time-to-log for generated python SDK output formatting.

🔬 Measurement:
Verified correctness via make check and make test-generator. The code performs the identical logic but uses fewer allocations.

… in python SDK builder output parsing

Optimized `xdk-build/src/python.rs` by replacing `split("\n").collect::<Vec<&str>>().into_iter()` with direct `.split('\n')` iteration, and replacing the intermediate space split collection with direct element matching, saving multiple `O(N)` heap allocations per formatter run.
