refactor: move CLI source modules to crewai-cli package

Copy all CLI source modules from lib/crewai/src/crewai/cli/ to the
new lib/cli/src/crewai_cli/ package, updating internal imports from
crewai.cli.* to crewai_cli.* throughout.

Includes: authentication, deploy, enterprise, organization, settings,
tools, triggers, templates, and all top-level CLI command modules.

Also excludes lib/cli/ from pre-commit mypy checks to match existing
behavior (original CLI code has the same type gaps).
