## What / Why This PR finishes the desktop refactor: the Tauri app is now a thin shell that launches the web server as a sidecar and loads the UI from `http://127.0.0.1:<port>`. All real backend logic lives in `packages/web/server/index.js`; desktop Rust keeps only native integrations (menu/dialog/notifications/updater/deep-link + window chrome). This unblocks: - consistent behavior across web/desktop/vscode (single backend) - simpler desktop maintenance (no duplicated Rust backend) - host switching between Local + remote instances in desktop - reliable cold-start behavior on slow machines (VSCode + desktop) ## Key changes - Desktop sidecar runtime - build pipeline to bundle web dist + `openchamber-server` sidecar (`packages/desktop/scripts/build-sidecar.mjs`) - robust local port selection (prefer saved/default, fallback to random; persisted in `~/.config/openchamber/settings.json`) - improved PATH handling so the sidecar can locate `opencode` CLI (incl `~/.opencode/bin`, overrides, common bins) - disable native right-click context menu in production builds (dev keeps it) - Desktop instance switcher (Tauri-only) - header button + modal to add/edit/delete remote hosts, set default, probe status/ping, switch back to Local escape hatch - auth gate includes host switcher so you can recover when a remote host is broken/auth-required - host list stored desktop-locally (not tied to the currently selected remote server) - Notifications - decision logic moved server-side; desktop notifications emitted via sidecar stdout and shown natively by Tauri - prevent double-notifications on desktop Local origin (UI ignores SSE notification when native path is active) - restore macOS notification sound - Updates - Tauri updater used only when viewing Local instance in desktop shell (avoid “remote web update” triggering desktop restart) - Settings persistence & UX polish - persist model favorites/recents via `/api/config/settings` (works for web + desktop; not origin-dependent) - persist per-project sidebar collapse state in `projects[].sidebarCollapsed` via `/api/config/settings` (with debounce on toggles) - macOS header sizing/traffic-lights offsets fixed (marketing macOS major injected from desktop; MultiRun header aligned) - VSCode cold-start: keep retrying provider/agent loads after connection to avoid empty UI on slow machines - misc lint/type fixes + bun.lock sync - Desktop bootstrap / resiliency - show onboarding screen when OpenCode CLI is missing (desktop Local origin), with retry hook to restart OpenCode after install ## Testing notes - Desktop (macOS): switch Local <-> remote, set default host, verify auth gate recovery, native notifications (with sound), updater gated to Local - Web: favorites/recents + per-project collapsed state persist across reload/restart - VSCode: slow startup no longer results in missing providers/agents/models
