### Overview
Major restructuring from monolithic `arcade-ai` package to modular
library architecture with standardized uv-based dependency management.

### New Package Structure
- **`arcade-tdk`** - Lightweight toolkit development kit (core
decorators, auth)
- **`arcade-core`** - Core execution engine and catalog functionality
- **`arcade-serve`** - FastAPI/MCP server components
- **`arcade-ai`** - Meta package that includes CLI functionality.
Optionally include evals via the `evals` extra. Optionally include all
packages via the `all` extra.
### Key Benefits
- **Lighter Dependencies**: Toolkits now depend only on `arcade-tdk` (~2
deps) vs full `arcade-ai` (~30+ deps)
- **Faster Builds**: uv provides 10-100x faster dependency resolution
and installation
- **Better Modularity**: Clear separation of concerns, consumers import
only what they need
- **Standard Tooling**: Eliminates custom poetry scripts, uses standard
Python packaging
### Migration Impact
- All 20 toolkits converted from poetry → uv with `arcade-tdk`
dependencies plus `arcade-ai[evals]` and `arcade-serve` dev
dependencies. When developing locally, devs should install toolkits via
`make install-local`.
- Modern Python 3.10+ type hints throughout
- Standardized build system with hatchling backend
- Enhanced Makefile with robust toolkit management commands
- Removed `arcade dev` CLI command
- Reduce the number of files created by `arcade new` and add an option
to not generate a tests and evals folder.
This foundation enables faster development cycles and cleaner dependency
chains for the growing toolkit ecosystem.
### Todo After this PR is merged
- [ ] Post-merge workflow(s) (release & publish containers, etc)
- [ ] Release order plan. @EricGustin suggests releasing in the
following order:
1. `arcade-core` version 0.1.0
2. `arcade-serve` version 0.1.0 and `arcade-tdk` version 0.1.0
3. `arcade-ai` version 2.0.0
4. Patch release for all toolkits (all changes in toolkits are internal
refactors)
- [ ] [Update docs](https://github.com/ArcadeAI/docs/pull/318)

# PR Description
## Summary
Changes include renaming the `arcade_gmail` toolkit to `arcade_google`,
adding unit tests for Google toolkit, add new tools to the Google
toolkit.
## Changes
### Makefile
- Added a new `make test-toolkits` target to iterate over all toolkits
and run pytest on each one.
### Added new tools for the google toolkit
1. `send_email`
This tool sends an email using the Gmail API.
2. `write_draft_email`
This tool creates a draft email using the Gmail API.
3. `update_draft_email`
This tool updates an existing draft email using the Gmail API.
4. `send_draft_email`
This tool sends a draft email using the Gmail API.
5. `delete_draft_email`
This tool deletes a draft email using the Gmail API.
6. `list_draft_emails`
This tool retrieves a list of draft emails using the Gmail API.
7. `list_emails_by_header`
This tool searches for emails by a specific header using the Gmail API.
- `sender`: The sender's email address to search for.
- `limit`: The maximum number of emails to retrieve.
8. `list_emails`
This tool retrieves a list of emails using the Gmail API.
9. `trash_email`
This tool moves an email to the trash using the Gmail API.
* Add new tool to the arithmetic toolkit for summation of a range.
* Add ability to attach debugger to cli. Use `.vscode/launch.json`'s
"Debug arcade dev" to do so.
* Fix issue in cli's main that used the incorrect url.
