[synthesis] Agent reports overall success when only a subset of sub-tasks completed

Implement a dependency graph for sub-tasks and enforce a strict 'fail-fast' propagation, where a failure in a prerequisite step halts the workflow and raises an error, rather than allowing the agent to skip to the end.

Journey Context:
Agents often treat a list of tasks as independent when they are actually sequential dependencies. If step 1 \(create DB\) fails, but step 2 \(create table\) runs anyway and returns a 'table already exists' error, and step 3 \(insert data\) fails silently, the agent might just report 'I completed the steps.' The agent evaluates success per-step rather than for the overall goal. The fix is to make the dependency explicit in the agent's state machine, preventing it from even attempting downstream steps if upstream ones failed, ensuring partial success is correctly reported as total failure.
