chore(ci): remove remaining claude automation

[Oddly]

Following on from #135, the rest of the Claude footprint goes. The mention-gated claude.yaml worked in principle but I am not getting enough value out of it to justify the surface area, especially given the recent rate-limit pressure on the underlying subscription. The client-side dry-run script and its triage.md prompt have no consumer once the workflow is gone, so they go in the same commit.

Coderabbit stays for PR review. The Claude GitHub App can be uninstalled from the repo at leisure — nothing in the tree depends on it any more.
