fix(visual-ml-model): point schema $id at the renamed Tools/ path

The $id is an identifier string (the validator loads the schema by
filesystem path), but commit 627c231 set it to the in-repo path; keep
it consistent with the renamed Tools/ directory.

NOTE: nodes/edges/groups are TOP-LEVEL (no 'graph' key) so this never collides with the ir_v1 structural validator.",
