This PR introduces the following changes:
- **Engine Environment Configuration**: Adds support for specifying an
environment variables file for the engine via the `arcade dev` CLI
command.
- **Configuration File Handling**: Refactors configuration file handling
in the CLI launcher to generalize logic for locating configuration
files.
- **Tool Execution Logging**: Enhances logging in `BaseActor` to include
execution duration and adjusts logging levels for better visibility.
- **Enhanced Tool Exception Handling**: Improves exception handling in
`ToolExecutor` and updates the `@tool` decorator to ensure proper
propagation and handling of exceptions raised during tool execution.
## Problem
I found a bug with `Github.CountStargazers` where a stargazer count of
`0` was interpreted as a null result. In other words, 0 wasn't passed
back to the Engine correctly.
Separately, the tool function was also not authorized correctly.
## Fix
- Don't use a falsy comparison when evaluating `result` inside the
`ToolOutputFactory`
- Add unit tests for `ToolOutputFactory` to give us confidence in the
business logic
- Added `ToolContext` to pass in the authorization token correctly.

This PR adds four new tools to the Google ToolKit
* `create_event`
* `list_events`
* `update_event`
* `delete_event`
I also improved an error log when tools are being registered by the
actor.
This PR also sneaks in an eval for gmail
Here is a sample conversation that shows the tools and their
capabilities and limitiations:
This PR includes several improvements to the Arcade client and adds
LangGraph examples:
1. Enhanced error handling in the Arcade client:
- Improved HTTP error handling in `BaseArcadeClient`
- Simplified request methods in `SyncArcadeClient` and
`AsyncArcadeClient`
2. Updated `ToolResource` class:
- Changed base path from `/v1/tool` to `/v1/tools`
- Added `tool_version` parameter to `authorize` method
3. Improved Toolkit discovery:
- Updated `find_all_arcade_toolkits` to search only in the current
Python interpreter's site-packages
5. Added LangGraph examples:
- New `langgraph_auth.py` example demonstrating Gmail authentication
- New `langgraph_with_tool_exec.py` example showing tool execution
within a LangGraph
6. Minor updates:
- Changed default `BASE_URL` to `https://api.arcade.com/`
- Updated import error message for eval dependencies

In this PR:
- Handle and require fully-qualified tool names `Toolkit.ToolName` in
the actor
Also, unrelated changes/fixes:
- Cleaned up the logic around actor secrets and `$ARCADE_ACTOR_SECRET`
- Removes experimental Flask actor for now
Note: Must be merged along with
https://github.com/ArcadeAI/Engine/pull/87
Fixes 2 issues that were causing CI to fail:
- Loading `config` in `eval.py` breaks because no API key can be found
in CI
- Python 3.11+ changed `Union` to `UnionType`
Added
- `arcade dev` - serves a simple fastapi actor
- `arcade config` - show/edit/change config in `~/.arcade`
- `arcade chat` - chat with LLM without toolcalls
Changed:
- `arcade show`, `arcade run` - can now use all installed toolkits
