Populate the repo with the Vault/OpenBao dynamic secrets engine that mints
LiteLLM virtual keys scoped by model, spending limit, and lease TTL.
- Secrets backend: config, roles, creds paths and a revocable litellm_key type
- LiteLLM API client (generate/update/delete/info) with master-key auth
- Unit tests (mock LiteLLM) and a docker-compose e2e against both Vault and
OpenBao proving the same binary works on each
- Makefile, woodpecker CI (build/test/pre-commit), pre-commit config
