⚠️ Breaking Changes

• ⚠️ eslint-plugin-template: add textContent to default allowList (f112c169)
• eslint-plugin: make component-selector and directive-selector configurations strict and clear (938362cb)
  The selector validation logic has been updated to be more strict and
  predictable:
  Default Prefix Change:
  • Both component-selector and directive-selector now default to prefix: 'app' to match
    Angular CLI defaults
  • This means selectors without the 'app' prefix will now fail validation unless a
    different prefix is explicitly configured
    Style and Prefix Validation Changes:
  • Single-word selectors (e.g., 'appselector') are now appropriately considered valid for
    both camelCase and kebab-case styles
  • Style validation is now completely independent from prefix validation
  • When a prefix is defined and found in a selector, the rule now correctly validates
    whether the prefix is properly separated according to the style:
    • For kebab-case: prefix must be followed by a hyphen (e.g., 'app-selector' ✓,
      'appselector' ✗)
    • For camelCase: prefix must be followed by an uppercase letter (e.g., 'appSelector' ✓,
      'appselector' ✗)
      Changes to error reporting:
  • Selectors that have valid style but improper prefix usage now report 'prefixFailure'
    instead of 'styleAndPrefixFailure'
  • Example: 'sgggg-bar' with prefix 'sg' and style 'kebab-case' now reports
    'prefixFailure' (valid kebab-case, but prefix not properly separated)
    Migration Guide:
  • If you have components/directives without prefixes that were previously passing, either:
    1. Add the 'app' prefix to your selectors
    2. Configure a different prefix that matches your existing selectors
    3. Explicitly set prefix: [] or prefix: '' in your ESLint config to disable prefix checking
       These changes make the rules more predictable and align better with developer expectations
       while maintaining compatibility with Angular's compiler requirements for web components.
