Project roadmap and task tracking for the nfx-stringbuilder library.

Todo

• Add convenience methods for common operations
  • substr(pos, len) for zero-copy access to portions
  • replace(pos, len, str) - in-place replacement
  • insert(pos, str) - insert at position
  • truncate(size) - limit output size

• Consider SIMD optimization for numeric conversions (may not be worth it - std::to_chars is already optimal)

• Consider compile-time format string validation (explore integration with std::format concepts)

In Progress

• NIL

Done ✓

• appendLine(str) / appendLn(str) - append with newline character (2026-02-08)
