shift_left_utils

Consolidates shift_left test coverage across UT, CLI, and IT layers using a CLI-first ownership model. Maps module functions to Typer commands, removes UT/core overlap, adds missing tests with lowest-level mocks, and updates CLI_IT_COVERAGE.md. Use when assessing or improving test coverage for project_manager, table_mgr, pipeline_mgr, or any shift_left cli_commands module; when reducing duplicate UT vs CLI tests; or when user mentions coverage overlap, CLI-first tests, or IT coverage gaps.
