### 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)

The CLI was starting the login process on the old domain, which is why
we were seeing a CSRF error. The cookie was placed on `arcade-ai.com`
not `arcade.dev`!
1. Fixes bug where arcade login doesn't work for localhost
- `arcade login -h localhost` will open login page at
`http://localhost:8000/...`
- Optionally specify the port: `arcade login -h localhost -p 8000`
3. Adds `local` flag to `arcade show`
- `-h localhost`, `-h 127.0.0.1`, and `-h 0.0.0.0` shows the tools that
are in the local engine's catalog
- `--local` show the tools that are in the local environment.
Adds:
- New options to `arcade chat`: `-h/--host`, `-p/--port`, and
`--tls/--notls`. This allows us to point `arcade chat` at a different
server than what's configured in `arcade.toml` which is very helpful for
debugging.
- Special case: if you do `-h localhost`, it will automatically use port
9099 and no TLS unless otherwise specified.
- Adds a non-fatal engine health check to `arcade chat` startup:
