[architecture] Race conditions and overwrites when multiple agents modify the same file simultaneously

Implement strict resource ownership where only one agent holds the write lock for a specific file or artifact at a time, enforced via a central state manager.

Journey Context:
Multi-agent systems often treat the filesystem as a shared blackboard, leading to race conditions where Agent A overwrites Agent B's changes. Optimistic locking is too complex for LLMs to resolve automatically, and branching per agent creates difficult auto-merges. The tradeoff is that strict ownership limits parallelism, but it guarantees state consistency and avoids irreversible overwrites.
