Code Review
This pull request optimizes the printer implementation in build/print.go by replacing the allocation-heavy printf method with specialized, more efficient methods: spaces, prints, and printc. Feedback suggests replacing the mutable global spaceBytes slice with an immutable const string to eliminate the risk of accidental mutation and ensure safety.
