ESLint Rule Extender Utility

eslint-rule-extender is a utility library designed to facilitate the extension and modification of existing ESLint rules without needing to rewrite them entirely. It provides a programmatic API to override aspects of an `ESLintRule` object, allowing developers to customize `meta` properties, add new AST visitors, or modify the reporting behavior of a rule. This can be particularly useful for creating highly specific linting rules based on established ones, or for adapting third-party rules to fit unique project requirements. As of version 0.0.1, it focuses on core functionality, offering a lean approach to rule customization. Its release cadence is not explicitly defined, but as a utility, updates would likely follow ESLint API changes or community-driven feature requests. A key differentiator is its focus on *extending* rather than *composing* rules, providing granular control over specific aspects.
