Barrett Ruth 597ec6bb2a feat(diff): propagate recurrence through buffer reconciliation
Problem: the diff layer does not extract or apply recurrence fields,
so rec: tokens written in the buffer are silently ignored on :w.

Solution: add rec and rec_mode to ParsedEntry, extract them in
parse_buffer(), and pass them through create and update paths in
apply().
