Henry	2281f00198	langchain: Standardize `output_parser.py` across all agent types for custom `FORMAT_INSTRUCTIONS` (#17168 ) - Description: This PR standardizes the `output_parser.py` file across all agent types to ensure a uniform parsing mechanism is implemented. It introduces a cohesive structure and common interface for output parsing, facilitating easier modifications and extensions by users. The standardized approach enhances maintainability and scalability of the codebase by providing a consistent pattern for output parsing, which can be easily understood and utilized across different agent types. This PR builds upon the foundation set by a previously merged PR, which focused exclusively on standardizing the `output_parser.py` for the `conversational_agent` ([PR #16945](https://github.com/langchain-ai/langchain/pull/16945)). With this new update, I extend the standardization efforts to encompass `output_parser.py` files across all agent types. This enhancement not only unifies the parsing mechanism across the board but also introduces the flexibility for users to incorporate custom `FORMAT_INSTRUCTIONS`. - Issue: https://github.com/langchain-ai/langchain/issues/10721 https://github.com/langchain-ai/langchain/issues/4044 - Dependencies: No new dependencies required for this change - Twitter handle: With my github user is enough.
