feat: shuma standalone — shell interactiva sobre Llimphi (front-door, git-dep al monorepo)

Shell con paridad zsh/fish, multiplexado y sesiones remotas nativas, en chasis
Llimphi de 4 slots. Front-door limpio: solo crates shuma-*/matilda-*; Llimphi y
lo fundacional (chasqui/minga discovery, pata-host, arje, hojas shared) por
git-dep del monorepo gioser.git — cero vendoring. shuma-discern se trae del
monorepo (lo necesita chasqui, evita doble-fuente). cargo check pasa (0 errores).

+# shuma
+
+> An interactive shell with zsh/fish parity — multiplexer and remote sessions built in — in Rust, on [Llimphi](https://gitea.gioser.net/sergio/llimphi).
+
+`shuma` replaces `zsh + tmux + mosh` with a single piece: a shell with history, completion and job-control, **native multiplexing** (no tmux), **remote sessions** (no mosh, no SSH daemon), all inside a Llimphi 4-slot chassis (TopBar · Main · BottomBar · Quake drawer). Optional `intent → command` inference layers an LLM on top — without it, the traditional shell runs unchanged. `matilda` is the sibling tool for declarative multi-host configuration.
+
+## Run
+
+```sh
+cargo run --release -p shuma-shell-llimphi   # the GUI shell (Llimphi chassis)
+cargo run --release -p shuma-cli             # CLI front-end
+cargo run --release -p shuma-daemon          # session daemon (local + remote)
+```
+
+## Architecture
+
+- **`shuma-core`** — shell engine: parsing, history, completion, job control. UI-agnostic.
+- **`shuma-shell-llimphi`** — the GPU chassis (4 slots + Quake drawer + command bar + launcher modules).
+- **`shuma-protocol` / `shuma-remote-exec`** — local-client ↔ remote-server over TCP/TLS, no SSH daemon required.
+- **`matilda-*`** — declarative multi-host config (the bare-metal sibling).
+
+## How dependencies work
+
+Clean front-door repo: it contains **only shuma's own crates**. Llimphi and every foundational dependency (content-addressed cards, P2P discovery via `chasqui`/`minga`, the `pata` panel host, `arje` process primitives, shared leaves) are pulled as git dependencies from the [`gioser`](https://gitea.gioser.net/sergio/gioser) monorepo — the suite's source of truth. No vendoring, no duplication; the first build clones the monorepo (cached afterwards).
+
+## Considerations
+
+- **Replacement, not addition.** With shuma you can drop zsh/tmux/mosh — the behavior is covered.
+- Remote sessions use `shuma-protocol`, not an SSH daemon.
+- Cross-platform Llimphi UI; also runs inside the Wawa kernel.
