/**
* Tests a complex offline scenario: Client 0 goes offline, updates
* two files, then deletes one of them. Meanwhile Client 1 updates
* the file that Client 0 will delete. When Client 0 comes online,
* the reconciliation must handle:
* 1. A.md: local update (straightforward)
* 2. B.md: deleted locally + updated remotely (conflict)
*
* This exercises the offline reconciliation ordering:
* updates are enqueued before deletes, and coalescing with
* remote updates received during reconnect.
