fix: Load .env before importing tools to ensure environment variables are available

- Move load_dotenv() to run before importing tools
- Ensures SERPER_API_KEY and other env vars are set before tool modules initialize
- Tools can now properly reference environment variables from .env file
- Fixes issue where tools couldn't access .env variables at import time
- Add noqa comments for necessary late imports
