Report #27145

[synthesis] Agent executes a plan based on stale environment state because the file was modified between observation and execution

Re-read the target state immediately before executing a write operation, or use atomic transactions/patching if the environment supports it.

Journey Context:
Agents assume the world is static between their observation and action. In collaborative or dynamic environments, a human or another process might change the file. The agent then executes its now-invalid plan, causing merge conflicts or overwriting new code. Re-reading adds latency but prevents destructive overwrites.
