enhance-visitors

A utility library (v1.0.0, last updated 2016) for merging ESLint visitor objects, enabling shared logic across multiple ESLint rules. It provides a `mergeVisitors` function that combines visitor objects so that all handlers for a given node type run in first-to-last order, with `:exit` handlers in reverse. Commonly used in ESLint plugin development to avoid duplicating common AST traversal logic (e.g., detecting a package import). Stable, but largely superseded by modern ESLint's native support for multiple visitors or `linter-utils`. The package has low maintenance and no known issues.
