feat: add CI support for governance_observability

Adds run.sh with step-labelled execution of all three scripts.
Fixes agent_tracing.py to hard-fail on missing OPIK_WORKSPACE at
module load (consistent with use_case_team.py and data_governance_team.py).
Adds .gitignore for generated governance_extract_*.json output files.
