⚡ Bolt: [performance improvement]

[cloudesize67-cmd]

💡 What: Optimized string parsing and vector allocation in run_formatter within xdk-build/src/python.rs. Replaced string splits (.split("\n") and .split(" ")) with character splits (.split('\n') and .split(' ')), removed an unnecessary intermediate array .collect::<Vec<&str>>().into_iter(), and used a mutable iterator pattern match on .next() calls to pull the space-separated elements without vector allocation.

🎯 Why: The original implementation was building intermediate dynamic arrays (Vec) just to iterate or pattern match them immediately. This caused 1 + N unnecessary heap allocations (where N is the number of lines emitted by the formatter).

📊 Impact: Reduces heap allocations and overall execution time of the logging loop by avoiding unnecessary Vec structures.

🔬 Measurement: Verify by running make test-generator and make check. They should pass successfully as the functionality remains functionally identical.
