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.

-`docs/WORKTREES.md` is the contract for session worktrees — placement,
-collisions, what blocks a kill, and what `--force` leaves behind. Read it
-before changing anything that creates or removes one.
-
-`docs/SIDEBAR.md` is the contract for session cards in the web and TUI
-sidebars — line layout, activity colours, duration format, state precedence.
-Read it before changing sidebar rendering.
-
-`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.

+//! Home-daemon broker handle (NAP-247, extended in NAP-327).
+//!
+//! The HTTP handlers use this to issue correlated request/reply RPCs over the
+//! daemon's single registry control link, keeping themselves thin:
+//!
+//! - `WS /api/attach/:id` → `resolve_attach`: resolve a peer-owned session into
+//!   an [`AttachCandidates`] (pair-scoped JWT + T2 perimeter info) (NAP-247).
+//! - `POST /api/sessions` / `DELETE /api/sessions/:id` for a peer target →
+//!   `forward_create` / `forward_kill`: relay the op to the owning daemon and
+//!   await its result (NAP-327).
+//!
+//! Each call correlates its reply by `reply_to`, fails fast while the link is
+//! down (NAP-263), and cleans up its pending entry on every exit path (NAP-259).

-//! Claude Code activity hook (#106).
-//!
-//! Two halves, both shared by the `maestro hooks install` CLI subcommand and
-//! the daemon's first-start auto-install:
-//!
-//! * [`HOOK_SCRIPT`] — the hook itself, written to disk at install time. It
-//!   posts an [`ActivityState`](maestro-protocol) to
-//!   `$MAESTRO_URL/api/sessions/$MAESTRO_SESSION_ID/activity` (#105). The same
-//!   global hook runs in every Claude Code session on the machine, so it exits
-//!   0 and silently when either #103 env var is unset, and it never lets a
-//!   daemon failure escape (short curl timeout, status ignored).
-//! * [`install`] — idempotent registration of that script in
-//!   `~/.claude/settings.json`. Only entries maestro itself wrote (identified
-//!   by [`HOOK_MARKER`]) are touched; every other hook and every other field
-//!   in the file is preserved verbatim.

+//! 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

+//! factor against anyone routing to the bind address; per spec §Auth the

+//!
+//! 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

-//! 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.
