Fix generator to create correct folder structure for install

The generator was creating e2e_helper.rb and app_commands inside the
framework subdirectory (e.g., e2e/cypress/app_commands), but they should
be at the install_folder root level (e.g., e2e/app_commands).

Changes:
- Move e2e_helper.rb from install_folder/framework/ to install_folder/
- Move app_commands/ from install_folder/framework/ to install_folder/
- Update initializer template to set install_folder without framework path
- Update VCR cassette path to use install_folder directly

This ensures:
1. Cypress/Playwright can find their config files via --project flag
2. Middleware can find e2e_helper.rb and app_commands at install_folder
3. Both frameworks can share the same helper and commands if needed

Fixes #201
