arcade new <name> --full generates an MCPApp (#787)
<!-- CURSOR_SUMMARY -->
> [!NOTE]
> **Medium Risk**
> Moderate risk because it changes the default `arcade new --full`
scaffolding (dependencies, entry points, Makefile workflow, licensing)
and removes interactive prompts, which could break existing expectations
for generated projects.
> 
> **Overview**
> `arcade new --full` scaffolding is simplified to be non-interactive
and always generate an `arcade_<name>` package, with derived name
variants (title/hyphenated) and updated next-step instructions (`make
install/dev/test/lint`).
> 
> The full template is updated to produce a runnable `arcade-mcp-server`
`MCPApp` (`__main__.py` + `project.scripts`), switch sample
code/tests/evals to a new async Reddit example tool (auth + metadata)
using `httpx`, and refresh dev tooling (new `Makefile`, ruff config
tweaks, added pytest `conftest.py`).
> 
> Template licensing/metadata is standardized to Arcade proprietary
(removes community/official conditionals and the templated README), and
the repo version is bumped to `1.12.0`.
>
