Now the LangchainTool can wrap:
* Langchain StructuredTool (sync and async).
* Langchain @Tool (sync and async).
This enhance the flexibility for user and enables async functionalities.

This is to support model path like :

The LLM occasionally includes an unexpected 'parameters' argument when calling tools, specifically observed with 'transfer_to_agent'. This change makes FunctionTool.run_async more robust by filtering arguments against the function signature before invocation.
This resolves issue #1637.
Update test_function_tool.py
fix typing
fix: add `from __future__ import annotations`
This change adds a new enum value which the agent builder can pass in the `BigQueryToolConfig` to allow limited writes to the `execute_sql` tool.

This change accepts the `google.auth.credentials.Credentials` type for `BigQueryCredentialsConfig`, so any subclass of that, including `google.oauth2.credentials.Credentials` would work to integrate with BigQuery service. This opens up a whole range of possibilities, such as using service account credentials to deploy an agent using these tools.

This change sets an explicit project id in the BigQuery client from the conversation context. Without this the client was trying to set a project from the environment's application default credentials and running into issues where application default credentials is not available.

1. let auth_handler.py to utilize the oauth2 credential fetcher to exchange token
2. restructure tool_auth_handler.py to support refresh token

This change introduces unit tests in which the behavior of the tool is asserted for various query types in various write modes through a mocked BigQuery client.

This allows to protect against any write operations (e.g. update or delete a table), useful for some agents that must only be used in a read-only mode, while the user may have write permissions.
