linter: False positive of `no-unused-private-class-members` when the private member is used in spread

[cnshenj]

What version of Oxlint are you using?

1.14.0

What command did you run?

oxlint -c ../.oxlintrc.json --tsconfig ./tsconfig.json src

What does your .oxlintrc.json config file look like?

{
  "$schema": "./node_modules/oxlint/configuration_schema.json",
  "plugins": [
    "typescript",
    "import",
    "unicorn"
  ],
  "categories": {
    "correctness": "off"
  },
  "env": {
    "builtin": true
  },
  "rules": {
    "no-unused-private-class-members": "error"
  }
}

What happened?

This following is reported as an violation of no-unused-private-class-members, which is wrong:

class Foo { private #privateMember: MyType; private func(): MyType { return { ...this.#privateMember }; } }

Adding a simple console.log(this.#privateMember); to func will fix it, which means oxlint doesn't properly recognize { ...this.#privateMember } as usage. eslint doesn't have the false positive.
