[synthesis] Partial success masking via step-wise commit without transaction rollback

Implement Saga pattern orchestration for multi-step agent workflows, where each step has a defined compensating transaction that undoes partial work if subsequent steps fail.

Journey Context:
Agent workflows often execute tool sequences sequentially without atomicity guarantees. When step N fails, steps 1 through N-1 remain committed, leaving the system in an inconsistent 'zombie state' \(e.g., file created but not indexed, database entry written but not linked\). Common mistakes include assuming agent steps are lightweight or atomic by default, or using simple try-catch without rollback logic. Alternatives like two-phase commit require resource locks incompatible with LLM latency. The Saga pattern accepts eventual consistency and defines explicit compensation logic \(e.g., 'if create\_file succeeded but index\_file failed, execute delete\_file'\) ensuring system returns to consistent state on failure.
