[architecture] Race conditions when multiple agents mutate the same file or state

Implement unambiguous resource ownership. Assign a single 'writer' agent to any given file, database table, or state key. Other agents must request mutations via the owner agent or a centralized state manager.

Journey Context:
In multi-agent coding tasks, agents often step on each other's toes, overwriting code or corrupting shared state. This leads to insidious, hard-to-reproduce bugs. By applying the Single Writer Principle—where only Agent A is allowed to modify auth.py and Agent B modifies api.py—you eliminate write conflicts. If shared state is absolutely necessary, use a transactional state store with reducers rather than direct mutation.
