fix: add missing 'project create' command to match v0.13.0 documentation

The v0.13.0 documentation references `basic-memory project create` in multiple places
but only `project add` was implemented. This commit adds the missing `create` command
with the same functionality as `add` to match the documented behavior.

Changes:
- Add project create command with name, path, and --default option
- Add test coverage for the new command
- Update error handling tests to include create command

Fixes #129
