[synthesis] Agent overwrites its own edits by referencing stale file context from earlier in the conversation

Re-read the modified file immediately after a write/edit operation before making further dependent edits. Do not rely on the pre-edit context snapshot.

Journey Context:
Agents try to be efficient by avoiding redundant reads. However, LLMs cannot mentally 'update' a previous context block. The pre-edit context remains highly salient. When generating the next diff, the model attends to the original, unmodified context, leading to contradictory code or overwriting the prior change. The cost of an extra read is vastly lower than the cost of a cascading merge conflict.
