Release v2.1.0

Fixed

• Bug: Removed a redundant is_array() check in es_optimizer_disable_emojis_tinymce() after adding a strict array parameter type, resolving a PHPStan always-true warning on PHP 8.3
• Critical: Fixed License URI in plugin header and readme.txt pointing to GPL 2.0 instead of GPL 3.0
• Critical: Fixed release workflow producing incomplete zip files missing languages/ directory and readme.txt
• Bug: Fixed changelog parser in release workflow that could not match ## [VERSION] heading format in CHANGELOG.md, resulting in empty release bodies
• Bug: Consolidated duplicate msgid entries in POT translation file and corrected license header
• Bug: Fixed CI lint step that never ran because it checked for .phpcs.xml or phpcs.xml.dist but the actual file is phpcs.xml
• Bug: Fixed README.md license text incorrectly stating GPL-2.0+ instead of GPL-3.0-or-later

Added

• Added uninstall.php to properly clean up plugin options from the database when the plugin is deleted
• Added section headers ("Performance Optimizations", "Header Cleanup", "Additional Features") to the settings page for better UX
• Split the monolithic plugin file into focused files under includes/

Code Quality

• Added phpcompatibility/phpcompatibility-wp to composer.json require-dev (required by phpcs.xml ruleset)
• Added scripts section to composer.json with lint:php and analyze commands for CI integration

Changed

• Modernization: Added modern PHP type declarations (parameter types and return types) to all functions
• Modernization: Replaced isset() ternaries with null coalescing operator (??) in render helpers
• Code Quality: Standardized all option-checking to use empty() with early-return pattern
• Code Quality: Consolidated duplicate domain validation, rejection notice, and output functions into shared helpers (es_optimizer_validate_domain_list(), es_optimizer_show_rejection_notice(), es_optimizer_get_validated_domains())
• Code Quality: Replaced hand-written resource hint output with the native WordPress wp_resource_hints filter
• Code Quality: Replaced deprecated HTML valign="top" attribute with standard <tr> (WordPress form-table CSS already handles alignment)
• CI: Updated Node.js from EOL version 16 to LTS version 20 in continuous integration workflow
• Docs: Corrected GEMINI.md and readme.txt feature lists to only include actually implemented features (removed references to XML-RPC, REST API restriction, auto-embeds, and Gutenberg CSS)
• Docs: Raised the documented WordPress baseline to 6.8+ across plugin metadata and contributor guidance
• Docs: Updated POT translation file with correct line references and added new translatable section header strings
• Tooling: Expanded .gitignore coverage for local instruction files, IDE settings, caches, logs, temporary files, dependencies, and distribution artifacts
• Security: Removed phpcs:ignore suppression on resource hint output by using the native WordPress resource hint API
• Security: Replaced fragile substring crossorigin detection (fonts.g, gstatic) with exact hostname matching against fonts.googleapis.com and fonts.gstatic.com
