feat(maestro): add just dev full-stack recipe and fix dev attach proxy

`just dev` builds maestro and runs the whole local stack in one command — registry (:8080), daemon (:7070), and the Vite web UI (:5173) — waits for each to be healthy, and tears all three down on Ctrl-C. Previously the Justfile only had frontend/CI recipes; running the project meant hand-starting the registry and daemon in separate terminals. Also fix attach under the Vite dev server: `/api/attach/:id` is a daemon-served broker WebSocket (NAP-243), not a registry route, so the old catch-all `/api` proxy sent it to the registry and got 404. Route `/api/attach` to the daemon (overridable via MAESTRO_DAEMON) and keep everything else on the registry — the same split the production maestro-web binary does. Verified: handshake now returns 101 and PTY bytes stream. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

-**No authentication layer, no registry, no peer-to-peer.** Whoever can reach the

-WireGuard/LAN address to share with their own devices, never a public IP.
-
-Every config field has a default, so `~/.config/maestro/config.toml` is

+`docs/superpowers/specs/2026-05-24-maestro-design.md` is the source of truth for architecture, wire protocol, session model, auth, repo layout, and scope boundary. **Read it before writing any code in this repo.**

 See `docs/INSTALL.md` for end-user install instructions.

-`nix run .#dev` (or `just dev`) brings up the whole local stack under
-process-compose: a debug daemon on 127.0.0.1:7071, then Vite on :5173 once the
-daemon answers `/api/info`. The SPA proxies `/api/*` back to the daemon, so only
-the UI is exposed on the network. The dev port is deliberately not the daemon's
-own default 7070 (`devDaemonPort` in `flake.nix`), so the stack never fights a
-real daemon on the same host.
-
 ## Conventions

 - **TDD by default.** Failing test first, then minimal impl. Commit test + impl together.
 - **Frequent commits.** One logical unit per commit; don't pile work up.
 - **Conventional commits with `maestro` scope.** Example: `feat(maestro): add Hello message round-trip test`.
- **`cargo fmt` + `cargo clippy --all-targets -- -D warnings`** before every commit.
+- **`cargo fmt` + `cargo clippy --all-targets -- -D warnings`** before every commit. (Add to CI as part of NAP-211.)
 - **Integration tests use real `tmux` and `git`.** Don't mock them. Isolate via temp `$HOME` and `TMUX_TMPDIR`.
+
+## Network assumption
+
+Maestro is network-agnostic. The operator chooses bind addresses; the perimeter is whatever VPN (Wireguard, etc.) or private LAN they've set up. Maestro does not terminate TLS itself or police the network. See spec §Auth.
+
+## Status
+
+Empty repo. Spec approved and committed. **NAP-211 is the natural start.**

 //! Public dispatch for the `maestro` CLI subcommands.
 //!
-//! Every command talks to the local daemon (`[cli].daemon_url`, default
-//! `http://127.0.0.1:7070`): `list` reads its session catalog, `spawn` / `kill`
-//! hit its session endpoints, and `attach` opens `WS /api/attach/:id`.
+//! Extracted from the per-binary `main.rs` (NAP-245) so the umbrella `maestro`
+//! binary can dispatch to the same logic.
+//!
+//! ## Transport (NAP-244)
+//!
+//! The CLI talks to its **home daemon** (`[cli].home_daemon_url`, default
+//! `http://127.0.0.1:7070`) and lets the daemon broker the rest:
+//!
+//! * `list` reads the daemon's local catalog mirror (own ∪ peer sessions).
+//! * `spawn` / `kill` hit the daemon's local session endpoints.
+//! * `attach` opens the daemon's `WS /api/attach/:id` broker, which picks the
+//!   transport and dials the target (the target verifies the registry-minted
+//!   pair-attach JWT — session binding, not a per-peer allow-list).
+//!
+//! If the home daemon is **unreachable** (connection refused / not running),
+//! every command falls back to the legacy registry path (registry HTTP +
+//! direct WS) with a one-line stderr warning, so migration is painless. As of
+//! NAP-327 the daemon brokers cross-daemon create *and* kill over the registry
+//! control link, so those no longer need a fallback — only an unreachable home
+//! daemon does.

+//! The result reads like a marking on a score — `allegro-cello`,
+//! `crescendo-oboe`, `staccato-viola`.
+//!
+//! ## Determinism
+//!
+//! Every pure path takes an **injected** [`rand::Rng`]; nothing here reaches
+//! for `thread_rng()` or the clock, so seeded tests are reproducible (a repo
+//! invariant). [`generate_thread`] is the one impure convenience wrapper for
+//! production callers that just want a name and don't care about the seed.

+//! The Rust generator is the source of truth. If the web UI wants an instant
+//! client-side reroll it can mirror [`ADJECTIVES`] / [`NOUNS`] verbatim, but

+//! Cookie-based auth for the client-facing HTTP/WS surface.
+//!
+//! On the first request the registry sets an httpOnly cookie whose value is a
+//! JWT signed with the shared token (`MAESTRO_TOKEN`, HS256). Subsequent requests
+//! must present a cookie whose signature verifies; missing or tampered
+//! cookies get a fresh cookie issued (effectively re-bootstrapping a
+//! first-time client) and are still allowed through. The cookie is the second
+//! factor against anyone routing to the bind address; per spec §Auth the
+//! perimeter is the operator's network.
+//!
+//! Implementation notes:
+//!
+//! - We reuse `jsonwebtoken` so we don't pull in a cookie/HMAC crate just for
+//!   this one signature.
+//! - The middleware passes the inbound `Cookie` header through to the inner
+//!   handler unchanged, and adds a `Set-Cookie` response header if the inbound
+//!   cookie was missing or invalid.

-//! An in-memory Maestro daemon for tests.
-//!
-//! Serves the real `/api/*` surface from `maestro-protocol` types, backed by a
-//! `Vec<Session>` instead of tmux. Use it whenever the subject under test is a
-//! client — request building, error decoding, the catalog reducer, the proxy —
-//! rather than session management itself. Tests that genuinely need tmux belong
-//! in `maestro-e2e` against a real daemon.
