tests/lib/rules/no-negated-condition.js:37

• Add tests for negated conditions in structural directives like v-if and v-show (e.g., <div v-if="!foo">) to ensure the rule flags those cases.

docs/rules/no-negated-condition.md:16

• [nitpick] Include a dedicated ## Examples section with clear code blocks showing valid vs. invalid negated conditions in templates for better developer guidance.

This rule is the same rule as core [no-negated-condition] rule but it applies to the expressions in `<template>`.
