refactor: remove cli/ from crewai package and relocate to proper modules

Move framework infrastructure out of crewai/cli/ to dedicated modules:
- cli/authentication/ → crewai/auth/
- cli/config.py → crewai/settings.py
- cli/constants.py → crewai/constants.py
- cli/plus_api.py → crewai/plus_api.py
- cli/version.py → crewai/version.py
- cli/crew_chat.py → crewai/utilities/crew_chat.py
- cli/reset_memories_command.py → crewai/utilities/reset_memories.py
- cli/utils.py (framework parts) → crewai/utilities/project_utils.py

Delete CLI-only duplicates (command.py, git.py, provider.py) already
present in crewai_cli. Replace _login_to_tool_repository with a
_post_login() hook in AuthenticationCommand. Update all imports and
mock.patch paths across both packages and tests.
