Description

Can't find json output for dmsd memory snapshot compare. Would also be neat if there were a dmsdj all or something that would compare for any changes in memory across all known snapshots.

The first part is likely the more important for automating what happened within a given time of execution. The second would just be convenience.

Research direction
The issue requests JSON output for dmsd memory snapshot compare and a convenience command dmsdj all. Examine the existing dmsd implementation in radare2's source code, likely in libr/core/cmd debug.c or similar files. Look at how other commands produce JSON output (e.g., using r json API) to replicate that pattern. The issue has no current activity; no PRs or comments provide guidance. Start by understanding the snapshot data structures and the comparison logic.
