Fix iOS build to respect cleanup_exclude_files config

[billythekid]

Summary

The iOS build's removeUnnecessaryFiles() method was using a hardcoded list of directories to remove, ignoring the user-configurable cleanup_exclude_files setting in config/nativephp.php.

Problem

This caused issues when users had large directories that should be excluded from the bundle, resulting in the zip process timing out during native:run ios.

Solution

This change:

1. Adds support for the cleanup_exclude_files config option, bringing the iOS build in line with the Android build which already respects this config via PreparesBuild.
2. Handles both files and directories from the config - using File::deleteDirectory() for directories and unlink() for files.
3. Handles null config values gracefully with null coalescing (?? []).

Changes

• src/Commands/BuildIosAppCommand.php: Updated removeUnnecessaryFiles() to read from config('nativephp.cleanup_exclude_files') and handle both files and directories
• tests/Feature/IosBuildCleanupTest.php: Added 7 tests covering the cleanup behavior

Tests

All 7 new tests pass:

• Removes default unnecessary directories
• Removes user-configured directories from cleanup_exclude_files
• Removes both default and user-configured directories
• Handles empty cleanup_exclude_files config
• Handles null cleanup_exclude_files config
• Handles nested directory paths in config
• Skips non-existent directories without error

I'd defer to the subsequent PRs you've linked here. I have a gut feeling there was another thing I missed in this I meant to return to and never did that bit me again.

Happy to have this closed as a wontfix/favoured other PR.
