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>

+`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.**

 ## Where the work is

-Gitea issues on [`naps62/maestro`](https://git.naps.pt/naps62/maestro), grouped
-into milestones.
+Linear project **Maestro** under team **Naps62**. Issues `NAP-211..218` cover the prototype; each has `blockedBy` set so the dependency chain is explicit. **`NAP-211` is the only unblocked starting point.**

-`.claude/linear.json` (legacy filename, `tracker: gitea`) wires `/yolo` and
-`/work` to that tracker — they pick from open, unassigned issues whose
-dependencies are all closed. `/blitz <milestone>` sweeps a whole milestone.
-
-Labels carry one value per axis: `area/*`, `type/*`, `difficulty/*`.
-`difficulty` drives model selection downstream, so it tracks the shape of the
-work, not its size.
+`.claude/linear.json` wires `/yolo` and `/work` to this project — they pick from "available now" (status backlog/pending, not blocked).

 ## Repo layout

 Cargo workspace. NAP-245 unified the per-binary crates behind a single
 `crates/maestro/` umbrella that ships the `maestro` binary with feature gates
-(`cli` / `daemon` / `tui` / `web`, default = all four).
+(`cli` / `daemon` / `registry`, default = all three). The library crates kept
+their existing shape; only the per-binary `main.rs` files were retired.

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

-`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.
-
-`docs/PREVIEW.md` is the contract for what the content pane shows while the
-operator moves the sidebar highlight — what a preview may touch, what ends it,
-what commits it. Read it before changing sidebar-driven navigation.
-
-`docs/RESTART.md` is the contract for what clients do when the daemon restarts
-or is upgraded under them — the build stamp on `/api/info`, the status
-indicator's states, the blocking overlay, grace and poll timings. Read it
-before changing reconnect behaviour on either client.
-
-`docs/COMMAND-BAR.md` is the contract for the `ctrl-k` command bar in both
-clients — how it opens, the sigils, the key model, the match-and-rank algorithm
-the two matchers must agree on, and the fixture table they are tested against.
-Read it before changing either bar or either matcher.
-
-`docs/STRUCTURED-VIEW.md` is the contract for a structured session (an agent
-run as a daemon child over ACP instead of in a tmux pane) — the eight
-transcript row kinds, the two projections and their cursor/replay semantics,
-the handshake and declined capabilities, and the approval nonce rules. Read
-it before changing anything that renders a structured session.
-
-`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.**

-#
-#   Gradle start up script for POSIX generated by Gradle.
-#
-#   Important for running:
-#
-#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
-#       noncompliant, but you have some other compliant shell such as ksh or
-#       bash, then to run this script, type that shell name before the whole
-#       command line, like:
-#
-#           ksh Gradle
-#
-#       Busybox and similar reduced shells will NOT work, because this script
-#       requires all of these POSIX shell features:
-#         * functions;
-#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
-#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
-#         * compound commands having a testable exit status, especially «case»;
-#         * various built-in commands including «command», «set», and «ulimit».
-#
-#   Important for patching:
-#
-#   (2) This script targets any POSIX shell, so it avoids extensions provided
-#       by Bash, Ksh, etc; in particular arrays are avoided.
-#
-#       The "traditional" practice of packing multiple parameters into a
-#       space-separated string is a well documented source of bugs and security
-#       issues, so this is (mostly) avoided, by progressively accumulating
-#       options in "$@", and eventually passing that to Java.
-#
-#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
-#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
-#       see the in-line comments for details.
-#
-#       There are tweaks for specific operating systems such as AIX, CygWin,
-#       Darwin, MinGW, and NonStop.
-#
-#   (3) This script is generated via the Gradle "wrapper" task
-#       (see https://docs.gradle.org/current/userguide/gradle_wrapper.html)
-#       within the Gradle project.
-#
-#       You can find Gradle at https://github.com/gradle/gradle/.

 //! 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.

-//! Two build-time jobs for the daemon.
-//!
-//! **Build stamp.** Records the commit the binary was built from, so

-//! sources, in order:
-//!
-//! 1. `MAESTRO_BUILD_COMMIT` / `MAESTRO_BUILD_DATE` / `MAESTRO_BUILD_DIRTY` in
-//!    the environment. The Nix build has no `.git` in its source tree (crane
-//!    filters it out), so `flake.nix` passes the flake's own revision this way.
-//! 2. The git checkout the crate is being compiled in.
-//!
-//! Neither available leaves the values empty; clients treat that as "unknown
-//! release" rather than an error.
-//!
-//! **SPA bundle.** Under the `web` feature only, resolve the directory
-//! `static_bundle.rs` embeds via `include_dir!` and publish it as
-//! `MAESTRO_WEB_BUNDLE_DIR`. Two modes:
-//!
-//! * `MAESTRO_WEB_DIST` set — the bundle was built elsewhere (Nix, CI, a
-//!   release pipeline) and that directory is embedded as-is. No node, no pnpm.
-//! * unset — the default developer path: run `pnpm install --frozen-lockfile
-//!   && pnpm build` in `web/` and embed `web/dist`. pnpm and node are HARD
-//!   requirements here; a missing toolchain fails with an actionable message

-//!
-//! The prompt is a user's own text, and it is handled as data throughout. It

-//! process table), it is never logged, and whatever comes back is reduced to
-//! a short slug by [`clean`] rather than trusted as a name.
