`pyproject.toml` version from `2.0.0` to `2.0.1`.

> Adds a minimal `contrib/langchain/Makefile` with an `install` target
that runs `uv sync` to standardize dependency setup.

<!-- CURSOR_SUMMARY -->
> [!NOTE]
> **Medium Risk**
> This is mostly a packaging/documentation change, but it is a breaking
change because the integration code and dependencies are removed, so any
consumers importing `ToolManager`/`AsyncToolManager` will fail at
runtime.
>
> **Overview**
> Marks `langchain-arcade` as **deprecated/inactive** and strips it down
to a stub package.
>
> The PR removes the LangChain/LangGraph integration implementation
(`manager.py`, `_utilities.py`), tests, and local dev tooling
(`Makefile`, `tox.ini`), and updates `README.md` to a deprecation notice
pointing users to `docs.arcade.dev`.
>
> `pyproject.toml` is bumped to `2.0.0`, clears dependencies, and
updates metadata/URLs; importing `langchain_arcade` now only emits a
`DeprecationWarning` and exports nothing.

Reverts ArcadeAI/arcade-mcp#759
<!-- CURSOR_SUMMARY -->
---
> [!NOTE]
> **Medium Risk**
> Adds a new LangChain/LangGraph integration layer that wraps and
executes Arcade tools, including authorization and error/interrupt
handling; bugs here could impact tool execution semantics for adopters.
Changes are mostly additive and scoped to `contrib/langchain`.
>
> **Overview**
> Re-introduces a standalone `contrib/langchain` Python package
(`langchain-arcade`) to expose Arcade tools as LangChain
`StructuredTool`s.
>
> Adds sync/async `ToolManager` implementations plus utilities to
generate Pydantic arg schemas from `ToolDefinition`, optionally rewrite
tool names (underscores vs dots), and handle authorization via LangGraph
`NodeInterrupt` or structured error responses.
>
> Includes packaging/dev scaffolding (`pyproject.toml`, `tox.ini`,
`Makefile`, `.gitignore`, `LICENSE`, `README`) and a comprehensive test
suite covering manager behaviors and auth flows.

<!-- /CURSOR_SUMMARY -->
Addresses general improvements to all toolkits including changing ruff
from python 3.9 to python 3.10 which is the reason for the removal of
Optional[] among others.
Also, turns out that our `make install` for toolkits wasn't correctly
checking for whether poetry was installed (&> /dev/null syntax isn't
supported by our check-toolkits GitHub action, so we were installing
poetry twice. I replaced with the more portable >/dev/null 2>&1)
Question: Should we also change ruff to py310 for the `arcade/` package
in a later PR?

# PR Description
* This PR updates code in `examples/` to be compatible with version
1.0.0
* This PR removes the Spotify examples since the Arcade hosted worker
doesn't currently cataloge the Spotify toolkit. We can reintroduce these
examples when it does.
* This PR performs various renames across the codebase for
`arcade-ai.com` --> `arcade.dev` and `Arcade AI` --> `Arcade`
