Excludes unnecessary folders and files

[nayanchamp7]

Summary

This PR improves PHPCS performance and consistency by excluding unnecessary directories from code sniffing.

Changes

Added exclude patterns to the ruleset file:

• vendor/
• node_modules/
• build/

<!-- Exclude unnecessary folders & files -->
<exclude-pattern>*/vendor/*</exclude-pattern>
<exclude-pattern>*/node_modules/*</exclude-pattern>
<exclude-pattern>*/build/*</exclude-pattern>

Why

These directories contain:

• Third-party dependencies
• Compiled/generated assets

They are not part of the plugin source code and should not be analyzed by PHPCS.

Benefits

• Faster PHPCS execution
• Reduced noise from irrelevant warnings/errors
• Consistent behavior across local, IDE, and CI environments

Impact

No impact on source code. Only affects linting scope.
