- delete api/requests.http and ARCHITECTURE.md (coordinator content)
- rewrite README.md and .env.example for the userservice
- drop dead RunPeriodic (reaper machinery userservice has no use for)
- fix .gitignore/.dockerignore/.golangci.yml module + artifact names
- degeneralize stale copied comments that said "coordinator"
Mirrors the coordinator workflow against a scimesh_users Postgres service.
Switches the test request helper to http.NewRequestWithContext so the noctx
linter passes on the go1.22 module.
