Subject: [PATCH] perf: check in neural patterns to avoid rebuild on every
 publish

- Add embeddedPatterns.ts to version control (544KB file)
- Add check-patterns.js script to detect when rebuild is needed
- Modify build scripts to only rebuild patterns when changed
- This avoids memory-intensive pattern embedding on every npm publish
- Patterns rarely change, so this significantly speeds up releases
