fix(maestro): dir autocomplete dismissal and key handling

Escape closes the popup, refocuses the input and stops propagation so it can't also discard a surrounding draft pane. Tab commits the highlighted entry and lets focus move to the next field. Blur / clicking outside dismisses, and a dismissed popup stays closed until the operator types again.

+A terminal-session orchestrator for one machine. One daemon per host owns every
 interactive shell or agent (Claude Code, opencode, plain bash) running on it;

-## Where the spec lives
+## Architecture

 ```
 **No authentication layer, no registry, no peer-to-peer.** Whoever can reach the
 daemon's bind address can drive every session on the host — same trust model as
 tmux itself. The operator picks the perimeter: `127.0.0.1` for local-only, a
 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
 optional.
 ## Where the work is
-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.**

 ```
 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. (Add to CI as part of NAP-211.)
+- **`cargo fmt` + `cargo clippy --all-targets -- -D warnings`** before every commit.
 - **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.**

 //! ## 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 sources feed this bus:

 //! 1. **Own-session events** — the daemon's `SessionManager::events()` stream,
 //!    translated from `SessionEvent` into the matching `RegistryEvent` variant
 //!    by [`spawn_session_publisher`].
 //! 2. **Peer-catalog events** — applied to the daemon's [`CatalogMirror`] when
 //!    the registry fans them out (NAP-246). `CatalogMirror::apply` publishes
 //!    each event here after mutating its local view.
 //!
 //! Subscribers get the merged stream. The `WS /api/events` handler builds a
 //! one-shot `Snapshot` of own ∪ peer state on connect, then forwards live
 //! deltas until the client disconnects. `Lagged` follows the registry's
 //! existing convention — clients resync via REST.

 //! Maestro is a conductor's podium for every shell you care about, so the

 //!
 //! ## Determinism
 //!
 //! Every pure path takes an **injected** [`rand::Rng`]; nothing here reaches

 //! 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

 //! 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.
