feat: create recommended eslint configuration

eslint-plugin/src/index.ts:73

• eslint-plugin/src/index.ts is truncated: the plugin object and syntax.create function are not closed, and there is no export. This will fail TypeScript compilation and prevents the plugin from being consumable. Restore the removed implementation and ensure the module exports the plugin object (and closes all braces).

      create: (context: eslint.Rule.RuleContext) => {
        const sourceFilePath: string = context.filename;
        // If eslint is configured with @typescript-eslint/parser, there is a parser option
        // to explicitly specify where the tsconfig file is. Use that if available.
        const tsConfigDir: string | undefined = getRootDirectoryFromContext(
          context as unknown as TSESLint.RuleContext<string, unknown[]>
        );

configs was added to IPlugin and recommended is imported, but this file currently doesn't define/export plugin.configs anywhere. To actually expose plugin:tsdoc/recommended, ensure the exported plugin object includes configs: { recommended } (and that the module exports plugin).

[Copilot]

This repo appears to consistently use named exports (no other export default usages were found). Consider exporting this as a named export (e.g., export const recommended = ...) to match existing module patterns and avoid any TS interop edge cases with default imports.

Suggested change

	const config: Linter.Config = {
	rules: {
	'tsdoc/syntax': 'warn'
	}
	};
	export default config;
	export const recommended: Linter.Config = {
	rules: {
	'tsdoc/syntax': 'warn'
	}
	};

[Copilot]

The new recommended config is a public entrypoint (plugin:tsdoc/recommended) but there’s no test covering that it is exported and contains the expected rule settings. Consider adding a small unit test asserting plugin.configs.recommended.rules['tsdoc/syntax'] === 'warn' so this contract doesn’t regress.
