[architecture] Race conditions and corrupted state when multiple agents concurrently write to the same shared resource

Implement unambiguous single-owner resource semantics; only the agent currently holding the lease can mutate the resource, or partition the state so each agent owns a disjoint slice.

Journey Context:
Shared mutable state is the classic concurrency nightmare, amplified by LLM non-determinism. If Agent A and Agent B both read a file, modify it, and write it back, one write gets lost. Alternatives like optimistic locking often fail because LLM workflows are long-running. Best call: strict ownership transfer or partitioned state \(e.g., Agent A owns frontend files, Agent B owns backend files\).
