Fails silently when `compilerOptions.incremental = true`

[chrisvasz]

When I set compilerOptions.incremental to true, this command fails silently with no output:

npx tsgo -p . --noEmit --extendedDiagnostics

Here's my whole tsconfig.json file:

{
  "include": ["."],
  "exclude": [
    "node_modules",
  ],
  "compilerOptions": {
    "incremental": true,
    "downlevelIteration": true,
    "lib": ["es2023", "dom"],
    "esModuleInterop": true,
    "forceConsistentCasingInFileNames": true,
    "jsx": "react-jsx",
    "isolatedModules": true,
    "noEmit": true,
    "noImplicitAny": true,
    "noImplicitOverride": true,
    "strict": true,
    "target": "es2020",
    "module": "esnext",
    "moduleResolution": "Bundler",
    "resolveJsonModule": true,
    "baseUrl": ".",
  }
}

If I remove the incremental: true line, the above command runs and gives diagnostic output.

It took me a bit to figure out exit code 7 is defined here for ExitStatusNotImplementedIncremental

Yeah, we should be printing an error, or better, just ignoring the option.

I just ran into this too, it took me a while to realize that I needed to disable incremental.

I'll send a PR quick that just removes this error and just runs the compilation normally.
