fix: use runuser for privilege drop and capture container stderr in logs

The container still exited immediately after the su-based fix.  can
interfere with TTY/stdin handling for interactive shells. Switch to
, which is root-only, skips PAM, and preserves file descriptors so
bash stays interactive.

Also improve container failure diagnostics:
-  now combines stdout and stderr
- This helps surface the real reason when a container exits with code 0

Quality gates:
- pytest tests/unit: 219 passed
- ruff: clean on changed files
- mypy: clean on changed files

Isolated unit testing with heavy mocking of external dependencies (Docker, Git/subprocess, databases, filesystem); tests follow arrange-act-assert pattern covering success paths, edge cases, error handling, and security concerns like path traversal prevention.
Standard Python unittest/pytest pattern with heavy use of mocking (subprocess, filesystem, database) to isolate components; tests are organized by service/domain with each file targeting a single module/class; no internal dependencies between test files.
