feat(maestro): let vite dev proxy honor \$MAESTRO_REGISTRY
`web/vite.config.ts` was hard-coded to proxy `/api` at
`http://127.0.0.1:8080`, so pointing the dev UI at a remote registry meant
hand-editing the file. Read `MAESTRO_REGISTRY` from the environment via
`loadEnv` instead, with the local default preserved. Accept either the HTTP
base URL (`https://…`) or the daemon-facing URL (`wss://…/daemon`) — the
latter is rewritten to `https://…` and the `/daemon` suffix stripped, since
the proxy needs the HTTP origin. Flips `changeOrigin: true` for HTTPS
upstreams so the proxied Host matches the cert.

maestro-web

Browser UI for Maestro. Connects to the registry HTTP/WS API for the catalog and to individual daemons (via direct WebSocket) for terminal I/O.

Framework choice: vanilla TypeScript

No frontend framework. The UI is small enough that the cost of pulling in Preact / Solid / Leptos doesn't pay back. xterm.js does all the heavy rendering; everything else is a session tree and a spawn form, both trivial in plain DOM.

This decision is non-architectural — swap in a framework later without touching the registry or daemon if needed.

Layout

src/
  main.ts        # entry point, hash-route dispatch
  api.ts         # registry HTTP API client
  events.ts      # `/api/events` WebSocket subscriber
  catalog.ts     # session tree view (groups by metadata.label)
  attach.ts     # xterm.js + daemon WS attach view
  spawn.ts       # spawn-session modal
  types.ts       # mirror of `maestro-protocol` JSON shapes
  styles.css     # mobile-first base styles

Routing is hash-based:

  • #/ → catalog
  • #/attach/<session-id> → terminal

This keeps the registry's static handler dumb (no SPA fallback needed). Concurrent attaches: open the same #/attach/<id> URL in another tab.

Dev

pnpm install
pnpm dev      # http://localhost:5173, proxies /api → http://127.0.0.1:8080
pnpm build    # → dist/, embedded into the registry binary at cargo build time

The Vite dev server proxies /api and the events WebSocket to a maestro-registry. Default is http://127.0.0.1:8080; point it elsewhere by exporting MAESTRO_REGISTRY before pnpm dev:

MAESTRO_REGISTRY=https://maestro-registry.example.com pnpm dev
# Daemon-facing URL also works — `wss://...` is rewritten to `https://...`
# and a trailing `/daemon` is stripped.
MAESTRO_REGISTRY=wss://maestro-registry.example.com/daemon pnpm dev

Direct daemon WS connections (for attach) bypass the proxy and use the URL returned by GET /api/sessions/:id/connect-info.

Production

pnpm build writes the bundle to web/dist/. The Rust registry crate embeds that directory via rust-embed at compile time and serves it from /. See crates/maestro-registry/src/web_assets.rs.
