fix: fix local dev could not reolve codegen-registry.ts

pnpm discover-plugins generates empty registries on Linux/local dev due to tsconfig path alias not resolving in CJS dynamic imports

Root cause summary:

• scripts/ has no "type": "module", so tsx runs discover-plugins.ts in CJS modeIn CJS mode, runtime await import("@/plugins/registry") bypasses tx's path alias transform
• This creates a separate module instance from the one plugins register into via ../registryResult: getAllIntegrations() returns [], all generated files have 0 entries, and lib/codegen-registry.ts is never written breaking pnpm dev with Could not resolve "../../../lib/codegen-registry" #126
