CLI --coverage.exclude filter throws TypeError

[iliketomatoes]

Describe the bug

I'm using Vitest in a monorepository (with vitest.workspace.ts), and it looks like the only way to provide coverage options is through CLI.

The command I use includes this filter: --coverage.exclude='**/node_modules/**', which causes Vitest to throw this error:

TypeError: resolved.coverage.exclude.push is not a function

Reproduction

In a monorepository that leverages Vitest Workspaces, run this command:

npx vitest run --coverage.enabled --coverage.lines=50 --coverage.functions=50 --coverage.branches=50 --coverage.statements=50 --coverage.all --coverage.include='packages/**' --coverage.include='apps/**' --coverage.exclude='**/node_modules/**'

You can provide coverage options inside a vitest.config.ts

I thought I was supposed to use defineProject (which doesn't support the coverage property) even at the root level. Thanks!

We should probably guard all possible properties with toArray method.
