Pull Request Overview

This PR adds support for specifying the Oracle client library directory via an environment variable, updates the database connector to accept and forward this directory when initializing in thick mode, and refines the async pool creation. It also updates configuration examples (including .env.example and README.md) and adds a Chinese translation of the README.

• Introduce ORACLE_CLIENT_LIB_DIR env var and pass it to DatabaseConnector
• Extend DatabaseConnector and DatabaseContext signatures to accept lib_dir
• Update oracledb.create_pool_async invocation and refresh documentation/examples
