[frontier] Cascading failures when coordinating multiple agents across distributed tool calls with partial execution

Implement the Saga pattern: replace distributed transactions with a sequence of local transactions where each step has a compensating action; use an orchestrator agent to manage the saga log and trigger rollbacks on failure.

Journey Context:
ACID transactions don't exist across LLM tool calls or external APIs. Naive retry logic leaves systems in inconsistent states \(e.g., charged but not booked\). The Saga pattern, originally from database literature \(Garcia-Molina, 1987\), is now critical for multi-agent flows. Each agent action becomes a saga step with a defined undo function. The orchestrator maintains a durable log \(often via event sourcing\) to ensure that even if the orchestrator restarts, it can resume or compensate. This beats 2-phase commit because it handles long-running operations and external services that don't support prepare phases.
