Move dotenv to local.ts entry point for V8 compatibility

- Create src/local.ts that imports dotenv and re-exports from index
- Remove dotenv import from src/index.ts (Smithery entry point)
- Update src/program.ts to import from local.js for CLI usage

This keeps src/index.ts clean for Smithery's serverless environment
while preserving dotenv functionality for local development.
