Scripts: a script chosen from File › Scripts reads its #include files and runs $.evalFile

File › Scripts ran an installed script as source text, so the run had no
file: an #include line ended it with "script file read refused", and
$.evalFile was refused too. The menu now checks the script as before and
runs it with script.run {path}, as docs/mcp.md describes, so its
included files and the files $.evalFile runs are read beside it.
