Enabling shell: true unconditionally makes this fix platform-wide. The Windows command is quoted above, but POSIX paths returned by resolveOpencodeCommand are now passed through /bin/sh unquoted and can still be split if they contain spaces. Please keep direct spawn(command, args, ...) behavior on POSIX and only enable shell mode for Windows, with a regression test for a Windows command path containing spaces.
