Stock AzerothCore does not ship CLAUDE.md, BUILD-NATIVE.md, or local build
logs at repo root. Park them under contrib/fractured-dev-extras/ so the
repo root stays close to upstream and dev clutter is contained.
- mv CLAUDE.md, BUILD-NATIVE.md -> contrib/fractured-dev-extras/
- mv build-worldserver.log + _build_paragon_*.log there (untracked / ignored)
- add contrib/fractured-dev-extras/README.txt explaining the layout
- gitignore: contrib/fractured-dev-extras/*.log
