+fix: enable clean imports from /scripts path with Hardhat compatibility
+
+Fixed npm package exports to enable clean imports:
+
+- Import from `@hashgraph/asset-tokenization-contracts/scripts` instead of `/build/scripts`
+- Added `typesVersions` field for legacy TypeScript `moduleResolution: "node"` compatibility (required by Hardhat)
+- Added missing runtime dependencies: `tslib` and `dotenv`
+- Removed duplicate export entry that caused confusion
+- Added package validation tools: `publint` and `@arethetypeswrong/cli`
+
+This maintains full compatibility with Hardhat v2 CommonJS requirements while providing proper TypeScript type resolution.
