BFlatandClaude Opus 5.5 435415770f M9: live sessions in the browser; join links and dialog polish (#106)
- Browser client (step 4): the web build joins sessions a desktop app hosts
  through the browser's WebSocket API (web-sys, binary frames, the same
  message encoding). Its connection logic is a target-independent state
  machine (collab-net driver.rs): hello on open, changes and presence held
  until the welcome, throttled presence, keep-alive pings, a silent host
  counted as dropped, reconnect with backoff, final refusals. Tested natively
  against a scripted socket and a real host over loopback. Hosting stays
  desktop-only (LiveLink::can_host; collab.peers canHost). https pages are
  told up front that they can only reach ws:// sessions on this computer.
- Shared join logic (join.rs: GuestConfig, outcomes, taking in host messages)
  and transport limits (limits.rs) used by the native guest and the browser.
- Invite links: `figcraft figcraft://join?...` joins on start (a bad link
  opens the Join dialog with it); file:// arguments are paths. Windows
  registers a per-user figcraft:// opener (HKCU\Software\Classes\figcraft)
  behind a Registry trait (tests use a fake): collab.registerLinks {on?} and a
  Preferences checkbox, default on for installed builds, never for builds
  from source. macOS Info.plist declares CFBundleURLTypes; the Linux desktop
  entry declares x-scheme-handler/figcraft and passes %U.
- Join dialog: Escape closes it and no longer reaches the canvas (selection
  kept); its field has the keyboard when it opens.
- Docs: collab-protocol (browser client, links, mixed content), mcp,
  control-protocol, README, web hosting notes, collaboration wording in the
  progress docs (numbers unchanged).

//! FigCraft in the browser.
//!
//! Runs the same [`figcraft_ui_egui::FigApp`] as the desktop app through eframe's web runner
//! (wgpu: WebGPU where available, WebGL2 otherwise). Build with `trunk build --release` from this
//! directory; the site lands in `dist/web` (see `packaging/web/README.md`).
//!
//! Differences from the desktop app:
//! - no TCP control server (browsers can't listen on sockets);
//! - no native file dialogs yet: the session starts with one new document;
//! - links open in a new browser tab;
//! - live sessions: it joins sessions a desktop app hosts (File ▸ Join live session…) but can't
//! host one. A page served over `https://` can only reach sessions on the same computer
//! (browsers block `ws://` from secure pages); serve it over `http://` on a trusted network to
//! join from other machines.
//!
//! URL query flag: `?webgl` forces the WebGL2 backend instead of WebGPU.
