skill: consolidated openstack-cloud-ops snapshot for Chat/project upload ...

The Chat-side skill mount is stale (130 lines vs the repo SKILL.md 244 + 6
references; docs/audit/skill-divergence-20260725.md) -- it caused a failed clone
and a wrongly-shaped first handoff-pack draft this session. Chat's skill surface is
single-file, so this flattens SKILL.md + all references/ into ONE uploadable
document the operator can drop into the Chat project to replace the stale mount.

Point-in-time snapshot at HEAD 951ba9c; the authoritative copy stays
.claude/skills/openstack-cloud-ops/. Regenerate from the skill dir on change.
ASCII + LF byte-verified. Not loaded as a skill (loose file, not a skill dir).
