fix(vault): delete the restated consolidation page, not the vault

`Multi-Node Runtimes.md` (+257) restated launch material that
[[Qwen3.8 PP Deployment]] (build target, two-process RPC table, cache-prune
cron), [[Sample Script Set]] (runnable scripts), [[Ethernet Bandwidth Math]]
and [[Expected Performance]] already own, and mixed-vendor numbers owned by
[[x4-pair-experiment]]. Consolidation means the facts end up in ONE place, not
that a new page is written beside the old owners: the four stubs it replaced
were frontmatter-only (9 lines each) and needed no successor. Page trashed,
three inbound links repointed at the real owners.
