Build pipeline hardening: ErrorBoundary, no PHP copies, TS pre-flight

- ErrorBoundary.tsx wraps widget — crashes show fallback, not blank void
- build.sh v1.1.0: removed ALL PHP file copies (Chronicler deploys manually)
- Added set -e / set -u for fail-fast
- Added TypeScript pre-flight check (yarn tsc --noEmit) before build
- Added dynamic Blueprint controller detection via find
- Widget injection now wrapped in <ModpackErrorBoundary>
- Pre-commit PHP lint hook at scripts/pre-commit-hook.sh
