[synthesis] Silent partial failure in parallel tool execution

Implement all-or-nothing saga semantics for tool batches; strict error propagation with circuit breakers for partial failures

Journey Context:
Async execution improves latency but breaks the linear error handling model—exceptions may be logged but not propagated to the planner. Agents often lack transaction boundaries across tool calls, leading to "succeeding" with corrupted state. The tradeoff is performance vs consistency; saga patterns ensure that partial failures halt execution rather than creating ghost data that contaminates subsequent reasoning.
