Adds financial_reports.py tools module with 5 fusion-engine-routed
tools registered in TOOL_DISPATCH:
- fusion_run_report
- fusion_get_anomalies
- fusion_generate_commentary
- fusion_drill_down_report_line
- fusion_compare_periods
Each tool guards on 'fusion.report.engine' being in the registry and
otherwise returns a structured error so the chat agent can surface a
clear "module not installed" message.
6 new TransactionCase tests (including a TOOL_DISPATCH registration
sanity check).
