Fix v1.1.7 release package structure for WordPress compatibility

CRITICAL FIX: WordPress plugin directory structure

Previous issue:
- ZIP contained files at root level
- WordPress created directory based on ZIP name: wc-composable-product-v1.1.7/
- This caused version-numbered directory in wp-content/plugins/

Corrected structure:
- ZIP now contains wc-composable-product/ parent directory
- All plugin files inside wc-composable-product/ directory
- WordPress extracts to wp-content/plugins/wc-composable-product/ (correct!)

Changes:
- Recreated ZIP with proper directory structure using rsync + zip
- Package size: 410 KB (419,697 bytes) - slightly larger due to parent dir
- New SHA-256: 866e7dd34431f4c881629fd8b59ddd3a27c7a45b7324a3d88cd064a3e01c1b83
- New MD5: 871fbb3b910380c0e43bcf1538408eda

WordPress standard: Plugin ZIP must contain single parent directory named after
the plugin slug, with all files inside that directory.
