[synthesis] Orchestrator agent overwrites worker agent's changes due to stale context

Implement optimistic concurrency control or state re-fetching. Before any write operation, the orchestrator must explicitly call a \`read\` tool on the target file to refresh its context, comparing a local hash/timestamp before writing.

Journey Context:
In multi-agent setups \(e.g., manager \+ coder\), the manager delegates a task, the coder modifies \`app.py\`, and reports success. The manager, still holding the original \`app.py\` in its context, later decides to make a minor tweak and writes its entire stale version of \`app.py\` to disk, erasing the coder's work. There is no error thrown. The manager's context is a stale cache. This is a classic distributed systems problem \(write-write conflict\) mapped to LLM context windows. Treating LLM context as the source of truth rather than the filesystem is the root cause.
