Cache continuously invalidated with dynamic inputs

### Describe the bug

given a `vite.config.ts` that looks roughly like this:
```ts
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:
```shell
$ pnpm vp run --verbose build --mode development
$ vp build --mode development ○ cache miss: 'vite.config.ts' modified, executing

(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)
