Contributor guide

Research direction

Start by reading the ESLint plugin unicorn contributing guide (https://github.com/sindresorhus/eslint plugin unicorn/blob/main/.github/CONTRIBUTING.md). Look at existing rule implementations like 'consistent destructuring' for reference. The rule should detect conditional spreads using ternary vs && and enforce one style. The 'pass' and 'fail' examples in the issue define the expected behavior. No linked PR or assignee, so this is open for contribution.
