Daniel Covington bdb3987305 newLang: add the write-and-check demo scripts/demo-write-check.ps1 types each demo program into the Vim clone on x64sc (fresh copy of vim/work.d81), confirms the saved SEQ file matches its ASCII mirror, then runs demo/n8check.s on x128: a DEMO driver (not N128C) that asks for a file name and runs the current front end (source reader, lexer, names, parser) with on-screen diagnostics and NAME.ERR. good.n8 checks clean; bad.n8 reports its four intended errors.

Write-and-check demo

Shows the Nova128 workflow as far as it exists today: a program is typed into the Vim clone on the C64, saved to disk, and checked on the C128 by the compiler front end. No code is generated yet (epic E04), so nothing runs.

pwsh -File scripts/demo-write-check.ps1                  # good.n8 and bad.n8
pwsh -File scripts/demo-write-check.ps1 -Programs bad.n8

File	Purpose
`good.n8`	Valid program: interface, class with private field, `init`, interface call
`bad.n8`	Four errors: `init` with a result, `destroy` with a parameter, private field used from the program, undeclared name
`n8check.s`	DEMO driver (not `N128C`): asks for a file name, runs source reader, lexer, names, and parser, shows diagnostics, writes `NAME.ERR`

The script works on build/demo/demo.d81, a fresh copy of vim/work.d81 (the original is never written). x64sc and x128 run one after the other, never together. Demo sources must be lowercase with no quotes or backslashes, because they are typed through VICE's -keybuf.

Outputs in build/demo/: NAME-vim.png (the editor after :w), NAME-check.png (the C128 screen), NAME.seq (the file Vim wrote), and NAME.err.txt (the error file, when there are errors).
