  • Replaced O(n) shift loop + StringCopy/kalloc/kfree with O(1) ring
    buffer storing PChar pointers directly (zero allocation).
  • Eliminated mod operator (causes int64 promotion + broken RTL helpers
    on i386 bare-metal); uses pure uint32 branch arithmetic.
  • Removed dead code: PTracerEntry/TTracerEntry linked list types,
    head/tail PTracerEntry vars, c_lock boolean
  • Dropped lmemorymanager and serial from uses clause
  • pop_trace remains as no-op stub for ABI compat
  • get_trace_N uses underflow-safe index: if head >= idx then
    head - idx else MAX_TRACE - (idx - head)
  • Added print_traces debug helper
