Introduces docs/manager/ with two design documents:
- README.md: high-level architecture for bm, a single-binary
operational control plane that ships as both a direct CLI and a
long-running `bm server` exposing an HTTP API and embedded web UI.
Covers the product model, distribution and packaging strategy,
agentless SSH cluster management, and a phased delivery plan
(Phase 1 manager foundation, Phase 2 CLI, Phases 3-4 progressive
mc replacement). Implementation-level subsystems, task model,
storage, and repository layout are kept in an appendix so the
high-level design reads cleanly.
- phase1-web-ui.md: wireframe-level web UI design for the first
release, scoped to the two operator journeys that only bm can
serve — deploying a new Buckit cluster on fresh hosts, and
migrating an existing MinIO deployment in place via binary swap.
Includes screen catalog, supporting operational surfaces, an
out-of-scope list that defers to the per-cluster Buckit console
for data-plane operations, and appendices covering the MinIO
compatibility surface and the package install path.
