claude: Fix create-project to not pass non-existent dir to initialization

The create-project command was passing the to-be-created project directory
to initializeProjectContextAndEngines(), which then tried to stat the
directory in projectContext(). This failed because the directory doesn't
exist yet - it's about to be created by the command.

Solution:
- Call initializeProjectContextAndEngines() without arguments
- This uses current working directory instead of the new project directory
- Engines are registered without needing the non-existent project context

The initialization only needs to register engines, not load project config
from the new directory (which doesn't exist yet and wouldn't have config
anyway).

Fixes test: smoke/project/project-simple.test.ts
