/**
 * Per-path in-memory buffer for the last-failed replace_window edit's
 * proposed content + search string. Used for the `edit_note({ from_buffer:
 * true })` recovery path — when an edit fails with NoMatch, the agent can
 * retry via the buffer with a lowered fuzzy threshold without having to
 * re-emit the potentially-long content payload.
 *
 * MCP stdio transport is single-client per process, so a process-global
 * buffer is session-equivalent. If we ever add HTTP/multi-client transport
 * this needs to be keyed by session id — but that's a separate change.
