* feat: add license gating system with Lemon Squeezy integration
Add Community/Pro tier infrastructure:
- LicenseService singleton with Lemon Squeezy license API integration
- /api/license endpoints (GET info, POST activate/deactivate/validate)
- 14-day Pro trial activated automatically on first boot
- 72-hour periodic validation with 30-day offline grace period
- LicenseContext provider for frontend tier awareness
- License settings tab with activation UI and status display
- ProBadge and ProGate reusable components for feature gating
- requirePro per-route guard for backend Pro-only endpoints
- Proxy bypass for /api/license routes (local-only, never proxied)
* feat: add user profile dropdown and reorganize top navigation
- Create UserProfileDropdown component with settings, billing, theme
toggle (System/Light/Dark), documentation links, and logout button
- Remove logout button from sidebar header
- Remove standalone settings button from top bar
- Move theme toggle from Settings modal to profile dropdown
- Inject app version via Vite define from root package.json
- Add globals.d.ts for __APP_VERSION__ type declaration
* refactor(settings): remove appearance tab from settings modal
Theme toggle was moved to the User Profile Dropdown in the previous
commit. Remove the now-redundant Appearance section, its nav button,
and the unused theme/setTheme props from SettingsModal.
* feat: add fleet view dashboard and about settings section
Fleet Overview: aggregates all nodes into a card grid showing status,
container counts, CPU/RAM/disk usage bars. Pro tier unlocks stack
drill-down with auto-refresh (30s). Backend endpoints /api/fleet/overview
and /api/fleet/node/:nodeId/stacks query nodes in parallel.
About section in Settings: displays version, license tier, status,
instance ID, and links to docs/changelog/issues.
Sidebar perf fix: stack status fetches now run in parallel via
Promise.allSettled instead of sequential for-loop, significantly
reducing load time for nodes with many stacks.
Also removes version number from User Profile Dropdown (now in About).
* fix(ci): resolve Docker build and E2E test failures
- Copy root package.json into frontend build stage so vite.config.ts
can read the app version during Docker multi-stage build.
- Update auth E2E test: logout button moved into User Profile Dropdown.
- Update nodes E2E test: Settings button moved into User Profile Dropdown.
Two console errors on HTTP deployments with no functional impact:
1. Helmet's default Cross-Origin-Opener-Policy: same-origin is ignored
by browsers over HTTP but logged as a console error. Disabled via
crossOriginOpenerPolicy: false (same rationale as HSTS/COEP).
2. Vite's production build injects an inline module-preload polyfill
script blocked by script-src 'self'. Disabled via
build.modulePreload.polyfill: false — all modern browsers support
link rel="modulepreload" natively.
- Generic WebSockets (stats, exec) now connect to /ws?nodeId= instead of
the bare root so the upgrade handler detects the remote node and proxies
the WS connection to the correct remote Sencho instance.
- Vite dev proxy gains ws:true on /api and a new /ws entry so WebSocket
upgrades reach localhost:3000 during npm run dev.
- Backend WS message handler falls back to the default local node when the
nodeId in a proxied message doesn't exist in the local DB.
- Open App button now extracts the hostname from the remote node's api_url
instead of using window.location.hostname.
