Function cbm_win_utf8_argv

src/main.c:1134–1163

On Windows the CRT hands main() an argv encoded in the active ANSI code page, so a * non-ASCII CLI argument (e.g. a repo path like café_日本語_repo) is mangled before the * program ever sees it — the documented `cli index_repository " "` then fails with * "repo_path is required" (#423/#20). Rebuild argv from the wide command line * (GetCommandLineW → CommandLineToArgvW) and convert each elem

 * the original narrow argv). The returned block lives for the whole process (argv must
 * stay valid until exit), so it is intentionally never freed. */
