Jiayuan Zhang 8816e1669c feat(desktop): brand dev build as Multica Canary with bundled icon (#1210)
* feat(desktop): brand dev build as Multica Canary with bundled icon

pnpm dev:desktop ran under the stock Electron name and default icon,
making it indistinguishable from any other Electron dev app in the dock.
Set a Canary app name + userData path and point the macOS dock icon and
BrowserWindow icon at the bundled resources/icon.png so the dev build is
visually branded.

* feat(desktop): allow overriding renderer port via DESKTOP_RENDERER_PORT

Lets a second worktree run `pnpm dev:desktop` while a primary checkout
already holds the default Vite dev port 5173 — required to actually
exercise the "Multica Canary" branding in isolation.

* feat(desktop): rebrand Electron.app Info.plist so dev shows Multica Canary

app.setName() can't override the macOS menu bar title or Cmd+Tab label
— those come from CFBundleName baked into the running bundle's
Info.plist. Patch the bundled Electron.app's plist during `pnpm
dev:desktop` so dev launches read "Multica Canary" everywhere, not
"Electron". Idempotent; unlinks before rewriting so we don't mutate a
pnpm-store inode shared with other projects.

// Rebrand the bundled Electron.app's Info.plist so `pnpm dev:desktop`
// shows "Multica Canary" in the menu bar, Cmd+Tab switcher, and
// Activity Monitor. On macOS these titles come from CFBundleName at
// launch time — `app.setName()` cannot override them at runtime, so
// patching the plist in node_modules is the only working fix.
//
// Idempotent: runs on every dev launch and no-ops once the plist already
// matches. The patch is isolated to this worktree's node_modules — we
// unlink the file before rewriting so we never mutate a pnpm-store inode
// shared with another project.
