fix(maestro): collapse mobile drawer after spawning a session

mountSpawned now fires a CLOSE_DRAWER_EVENT so the sidebar gets out of the way once the new session lands. Covers fast-forward, modal, and command-bar spawn paths. Closes #261 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

 ## Where the work is

-Linear project **Maestro** under team **Naps62**.
+Gitea issues on [`naps62/maestro`](https://git.naps.pt/naps62/maestro), grouped

+`.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.

+//! is best-effort: a missing binary, a timeout, or an unusable answer leaves
+//! the generated handle in place.
+//!
+//! The prompt is a user's own text, and it is handled as data throughout. It
+//! goes to the child on stdin (never argv, where it would be visible in the
+//! process table), it is never logged, and whatever comes back is reduced to
+//! a short slug by [`clean`] rather than trusted as a name.

+//! What size the shared tmux window should be, given every client watching it.
+//!
+//! A tmux window has one size, but a session can have several clients attached
+//! at once — two browser panes, a browser and the TUI. Each reports the size
+//! *it* can display, and applying whichever arrived last makes the window
+//! flip-flop. Every flip forces a full-screen application (Claude Code, vim) to
+//! repaint at a new height, and the rows it drew at the old height are never
+//! cleared: the operator ends up looking at a stale input box, types into a
+//! box that is not where the screen says it is, and concludes the pane is
+//! stuck.
+//!
+//! So the window is sized to the smallest attached client on each axis — the
+//! same rule tmux uses for its own multiple clients, and the only size every
+//! client can render without truncation. The size last handed to tmux is
+//! remembered, so a report that changes nothing costs no `tmux` fork at all.

-Standalone HTTP server that hosts the Maestro browser UI and reverse-proxies
-to a co-located `maestrod`.
-
-```
-browser  ──HTTP──▶  maestro-web (:8080)  ──HTTP/WS──▶  maestrod (:7070)
-                         │

-                             /api/attach/:id, /api/events  proxied as WebSocket
-```
-
-## Trust model
-
-`maestro-web` does not authenticate anyone. Whoever can reach the bind address
-can use it. Pick the bind accordingly:
-
-| Bind                  | Reach                              | Use when                    |
-| --------------------- | ---------------------------------- | --------------------------- |
-| `127.0.0.1:8080`      | Local users on this host           | Default. Same as tmux.      |
-| `<wg-ip>:8080`        | Devices on your WireGuard mesh     | Phone/tablet over VPN.      |
-| `<lan-ip>:8080`       | Devices on your trusted LAN        | Home / lab networks.        |
-| Public IP             | Don't                              | — add real auth first.      |
-
-## Config
-
-The binary reads `~/.config/maestro/config.toml`. The `[web]` section:
-
-```toml
-[web]
-bind_addr        = "127.0.0.1:8080"      # default
-daemon_url       = "http://127.0.0.1:7070"  # default
-```
-
-Env-var overrides (all optional):
-
- `MAESTRO_WEB_BIND_ADDR`
- `MAESTRO_WEB_DAEMON_URL`
- `MAESTRO_WEB_DEV_PROXY_TARGET`
- `MAESTRO_CONFIG` — override the unified config-file path.
-
-## Build
-
-The SPA bundle lives in `../../web` and is embedded into the binary at compile
-time via `include_dir!`. Build the frontend first:
-
-```sh
-pnpm -C web install
-pnpm -C web build
-cargo build -p maestro-web --release
-```
-
-Or, from the repo root:
-
-```sh
-just web
-```
-
-A fresh checkout compiles even without `pnpm build` (an empty `web/dist`
-exists in-tree); the binary just serves a placeholder until the bundle is
-built.
-
-## Run
-
-```sh
-target/release/maestro-web
-```
-
-Then point a browser at `http://127.0.0.1:8080/`.
-
-## Development workflow for the frontend
-
-Use Vite directly so you get HMR. From `web/`:
-
-```sh
-pnpm dev
-```
-
-Vite serves on `:5173` and proxies `/api/*` straight to `maestrod` at
-`127.0.0.1:7070` (override with `MAESTRO_DAEMON_URL=...`). You don't need to
-rebuild the Rust binary while iterating on the frontend.
