(Migrated from github.com)

Parent: #2
Depends on: #7

Scope

Implement one durable mutation path for:

add, update, and remove node;
add, update, and remove edge;
move nodes;
set viewport/view state;
apply an atomic graph-operation batch.

Each command must validate against the current graph and type registry before producing a new graph state.

Acceptance criteria

Manual edits, imports, and future actions can use the same command interface.
Failed batches apply no partial mutations.
Removing a node handles attached edges deterministically.
Commands produce structured success or rejection results.
Unit tests cover every command and rollback path.
