fix(langchain): preserve open MCP object arguments (#40414) Some MCP servers expose a small set of gateway tools—such as list, describe, and call—instead of one tool per operation. Their call tool accepts a free-form object, but provider conversion can accidentally turn that argument into an object that accepts no fields. This change marks those direct free-form object arguments explicitly with `additionalProperties: true`, so models can send operation-specific keys through the gateway. It preserves constraints supplied by the MCP server and does not mutate the original schema. The normalization is intentionally narrow: it only examines direct tool properties rather than recursively walking every JSON Schema keyword. Six focused MCP schema tests pass; Ruff formatting/lint and mypy pass. No new dependencies or public API changes.
