Docs/add adeu integration

[Mikko Korpela (mkorpela)]

Overview

This PR adds the official integrations and provider documentation for the langchain-adeu third-party integration package.

Specifically, it:

1. Registers langchain-adeu in the packages.yml external integrations registry.
2. Creates the provider page at src/oss/python/integrations/providers/adeu.mdx.
3. Creates the tool guide page at src/oss/python/integrations/tools/adeu.mdx.

langchain-adeu integrates Adeu's local, offline-capable Microsoft Word (.docx) redlining and parsing capabilities as native LangChain tools. This allows LLM agents to safely read, edit, diff, and sanitize OpenXML files using a token-efficient Markdown representation with inline CriticMarkup, fully preserving native layouts, custom styles, and XML structures.

Checklist

• I have read the contributing guidelines, including the language policy
• I have tested my changes locally using docs dev
• All code examples have been tested and work correctly
• I have used root relative paths for internal links
• I have updated navigation in src/docs.json if needed

Additional notes

• Added langchain-adeu to the root-level packages.yml registry so that it compiles automatically into the overview.mdx provider table via partner_pkg_table.py during builds.
• Checked and updated src/docs.json navigation array to align sidebar routing structure (if needed).
• The package langchain-adeu has been officially published to PyPI (version 1.0.0). The codebase is fully verified and passing the canonical langchain-tests conformance suite for tools and toolkits.

Hi Mason Daugherty (@mdrxy)!

Pushed PR to add integrations and provider documentation for langchain-adeu.

langchain-adeu acts as a Virtual DOM for .docx files. LLM <-> MS Word connector.

The integration package has been published to PyPI (v1.0.0) and conforms to the langchain-tests suite. Locally, the pre-checks (packages.yml validation and table regeneration) have been run and are passing.

Hope you're having a restful Memorial Day and looking forward to your feedback when you're back!
