Describe the bug

given a vite.config.ts that looks roughly like this:

export default defineConfig(({command, mode}) => {
  // used by some vite plugin as a temporary directory
  const tempDir = `tmp/${mode === "production" ? "prod" : "dev"}`;

  return {
    run: {
      tasks: {
        build: {
          command: "vp build",
          cache: true,
          input: [
            {auto: true},
            `!${tempDir}/**`,
          ],
          output: [
            {auto: true},
            `!${tempDir}/**`,
          ],
        }
      }
    },
    // rest of vite config
  };
});

that is, when run in the production mode the input/output arrays are [{auto: true}, '!tmp/prod/**'], and when run in the development mode the input/output arrays are [{auto: true}, '!tmp/dev/**'].

if you run it the first time with --mode development, it will be a miss and will be properly added to the cache so subsequent runs with --mode development are cache hits.
however, if you then run it with --mode production, it will be a cache miss but it won't get properly added to the cache, so all subsequent calls with --mode production will also be cache misses.

you will get something along the lines of this:

(I am prefixing shell commands I ran with $, so to distinguish it from when $ was printed to the console, I added two spaces in front of it)

I have not provided a reproduction sample at the moment (I am aware that I checked the box at the bottom), I just want to report this before I forget. I'm going to make a reproduction sample later.
