feat: ledgrrr governance integration with MCP client, Rhai workflows, and E2E testing

- Add ledgrrr-mcp-client.ts for MCP stdio transport to ledgrrr-mcp-server
- Create Rhai workflow script (comic-generation.rhai) for three stages
- Integrate ledgrrr into agentic-comic-workflow for script generation governance
- Integrate ledgrrr into image-generate endpoint for rendering and forecasting
- Add database migrations for audit_log columns
- Create comprehensive E2E test framework and documentation
- Configure ledgrrr datums in _b00t_ directory for both MCP and CLI

Implements governance/audit trail for full A→B→C pipeline with Mermaid visualization.
Uses MCP stdio transport since ledgrrr not designed for library usage mode.
