Function cbm_build_win_cmdline

src/foundation/subprocess.c:285–300

Build a full Windows CreateProcess command line from a NULL-terminated argv, * applying the MS C runtime quoting rules so the child re-parses byte-identical * argv. Returns true on success, false if the result would overflow `buf`. * * Defined unconditionally (pure string logic, no Windows headers) so the quoting * contract is unit-tested on Linux/macOS CI too — even though the real spawn pat

 * containing a quote (e.g. the index JSON {"repo_path":"…"}), corrupting the
 * spawned child's argv. */
