fix(tools): Windows builds when paths contain spaces (prefix_map, ldgen, CI)

- Harden prefix_map.cmake for paths with spaces on Windows

- ldgen: fragments-list-file, list normalization, CMake integration (tools/cmake + cmakev2)

- CI exclude list for check_tools; test_spaces bundle tweak

Made-with: Cursor

tools/cmakev2/ldgen.cmake
