Avoid duplicate package checks in basectl check

   - File: `cli/python/base_setup/engine.py`
   - Problem: `run_command` captures stderr but leaves stdout inherited from the parent process, so `brew` and `pip` output appears live in the terminal but is absent from the persistent Base log.
   - Expected fix: either capture and log stdout, stream it while also preserving it for the log, or document live-only stdout as intentional behavior.

-- [ ] Avoid duplicate `pip show` calls in `basectl check`.
-  - File: `cli/bash/commands/basectl/subcommands/setup_common.sh`
-  - Problem: package checks call `setup_base_python_package_installed`, then `setup_base_python_package_check_message` calls it again, causing two `pip show` invocations per package.
-  - Expected fix: compute package presence once and pass the known status into message formatting.
