+Add support for configurable options on linter rules
+
+Linter rules can now define typed options with defaults using `defaultOptions`, and users can pass options when enabling rules in `tspconfig.yaml` or rulesets.
+
+**Defining a rule with options:**
+
+```ts
+const myRule = createRule({
+  name: "no-model-with-name",
+  severity: "warning",
+  description: "Bans models with a specific name",
+  messages: { default: "This model name is not allowed" },
+  defaultOptions: { bannedName: "Foo" },
+  create(context) {
+    return {
+      model: (target) => {
+        if (target.name === context.options.bannedName) {
+          context.reportDiagnostic({ target });
+        }
+      },
+    };
+  },
+});
+```
+
+**Configuring options in `tspconfig.yaml`:**
+
+```yaml
+linter:
+  enable:
+    # Enable with default options
+    "@typespec/my-lib/no-model-with-name": true
+    # Enable with custom options
+    "@typespec/my-lib/no-model-with-name":
+      bannedName: "Bar"
+```
