Capture OHM cleanup script and Claude dev config

scripts/cleanup-open-human-model.sh is the one-off used on
2026-05-25 to hard-delete the exploratory open-human-model RFC from
wiggleverse/meta, reserving the RFC #1 slot for the eventual `human`
RFC. Kept in-tree as the audit artifact for that removal.

.claude/launch.json captures the frontend dev-server invocation
(port 5180, --strictPort) so contributors and tooling can launch
the same way. .gitignore now excludes .claude/settings.local.json,
which is per-machine permissions and not appropriate to share.
