The desktop CSP listed only known embed hosts in frame-src, so every
room widget that is not one of them (Jitsi, Etherpad, Grafana, bots)
showed a blank frame; the web deploy allows https: frames (#205).
Match it. Widget frames are sandboxed by cinny and same-origin widget
URLs are refused (isWidgetUrlSafe), so this does not widen what a
widget can do to the app.
Fixes#33

On CachyOS the in-app update failed with "Permission denied (os error 13)
at path /usr/bin/tauri_current_app…": the app was installed from the
Arch package, and Tauri's Linux updater can only replace an AppImage — for
anything else it tries to write next to the binary in /usr/bin.
- update_install_kind command: "in-app" on Windows and for an AppImage
($APPIMAGE set); on Linux package installs "pacman" (ID/ID_LIKE arch:
Arch, CachyOS, Manjaro, EndeavourOS…), "deb" (debian/ubuntu and
derivatives) or "manual". The web UI shows the matching update command.
- install_update refuses up front on a package install
("install: package-managed (…)") instead of downloading the whole
update and failing at the last step.
Tests: CachyOS/Arch → pacman; Ubuntu/Debian/Mint → deb; Fedora/unknown →
manual; AppImage and Windows → in-app.

The example.com check could pass vacuously if the runner can't reach the
internet (goto failed silently, the mic request then came from the app's
own page). Serve a page on http://localhost:9333 instead, confirm the
navigation happened, and fail on builds that should refuse it.

The CI VM has no microphone (getUserMedia → NotFoundError). With
LOTUS_WEBVIEW2_DEBUG_PORT set the app also passes
--use-fake-device-for-media-stream; permission requests still go through
the real PermissionRequested handler.

WebView2's WEBVIEW2_ADDITIONAL_BROWSER_ARGUMENTS is ignored because the app
sets its browser arguments explicitly (seen on the runner: the WebView2
command line had only the app's arguments). The app now appends
--remote-debugging-port only when LOTUS_WEBVIEW2_DEBUG_PORT holds a valid
port (>= 1024); otherwise the arguments are exactly as before.

Adds the same `statusPages` entry the web app uses, so the desktop app
shows the status banner for matrix.lotusguild.org too (Kuma status page
https://isitup.lotusguild.org/status/matrix). The desktop CSP already
allows https: connections; no other change is needed. Inert until the
bundled cinny includes the banner (cinny PR #255).
Tested on a Linux release build: with a local fake Kuma reporting calls
down, the desktop app shows "Voice calls are down right now. Messages
still work." and polls both endpoints; from inside the desktop app the
real Kuma page answers 200 on both (CSP and CORS allow it).

Commands for the web client to keep a copy of the login tokens in the OS
keychain: secure_session_supported / _set / _get / _clear.
- Windows: Credential Manager via the keyring crate (3.6, windows-native),
entry "session" in service "Lotus Chat". Only the secrets are stored
(userId, deviceId, accessToken, refreshToken); the serialized value is
capped at 1200 chars (Windows' limit is 2560 bytes).
- Other platforms: supported = false and the other commands answer "not
supported on this platform" (Linux Secret Service can prompt to unlock a
wallet at startup; that needs its own testing). No new Linux dependency:
without a platform feature the crate only has its mock store.
- Keychain calls run on the blocking pool, off the main thread.
Step 1 is a mirror only (the web client still reads its session from
localStorage); see the cinny PR.
Tests: round trip + clear, clearing an empty keychain, incomplete and
oversized sessions rejected with nothing written, the JSON shape the web
client sends, a realistic OIDC session fits (keyring's mock store). Linux
release build: commands answer as designed and login is unaffected.
Windows: type-checked only.

The bundled Element Call page ran on the app's own origin
(http://localhost:44548), so the call frame could read the app's storage
(login token) and DOM. Serve it from http://127.0.0.1:44548 instead: the
same local server and bundle, a different origin.
- The local server binds 127.0.0.1 explicitly. The app is still loaded as
http://localhost:44548 (its storage stays where it is; the engines try
127.0.0.1 for `localhost`). Binding the name `localhost` could pick ::1
only (Windows lists it first), and then 127.0.0.1 wouldn't answer.
- config.json: desktopCallOrigin = http://127.0.0.1:44548. cinny loads the
call page from there only when this is set (cinny #43 PR).
- CSP frame-src allows http://127.0.0.1:44548.
- Permissions (on top of #22): the call page's origin gets microphone/
camera/screen only; nothing else.
- The call page gets no IPC: the capability only matches
http://localhost:44548.
Tested (Linux release build): the server listens on 127.0.0.1:44548 and
the app loads as http://localhost:44548; the call page loads from
127.0.0.1 inside the app under its CSP; from that frame parent.localStorage
and parent.document are SecurityError, while a same-origin frame (the old
setup) reads the app's storage. The call itself was tested in a simulated
desktop (Chromium, the WebView2 engine) against a local Synapse + LiveKit;
see the cinny PR. Rust tests 17 passed; Windows code type-checked.

Linux (WebKitGTK) allowed every permission request of every kind; Windows
(WebView2) auto-allowed mic/camera/notifications without checking who asked.
Now (src-tauri/src/webview_permissions.rs, unit-tested):
- Linux: microphone/camera/screen, device labels, notifications and location
are granted when the page in the window is the app
(http://localhost:44548; debug builds also the bundled/dev page).
Everything else is denied (WebKitGTK has no prompt of its own). WebKitGTK
doesn't say which frame asked; frames are gated earlier by the Permissions
Policy (cinny gives microphone/camera only to the same-origin call frame).
- Windows: the same grants (minus location, which keeps WebView2's prompt),
checked against the origin of the frame that asked (args.Uri()). Other
origins are denied mic/camera/notifications/location; other kinds keep
WebView2's default handling.
- Denials are logged ("webview: denied …").
Tested on Linux with a release build under Xvfb + PulseAudio (no WebDriver:
WebKit's automation mode bypasses the handler), before/after:
- app page: mic, device labels, location allowed (unchanged)
- same-origin call frame: mic allowed (unchanged)
- cross-origin frame without allow=: blocked before the handler (unchanged)
- foreign top-level page: mic, device labels, location now denied (were
allowed)
Real cinny build: boots, logs in, no denials. Windows code type-checked
(x86_64-pc-windows-gnu).

The 4.12.343 workaround (WEBKIT_DISABLE_DMABUF_RENDERER=1 + GDK_BACKEND=x11)
made the app launch but pushed every frame through shared memory under
XWayland: noticeably laggy at 3840x2058. The reporter's WAYLAND_DEBUG trace
showed the real cause on native Wayland:
wl_display#1.error(wp_linux_drm_syncobj_surface_v1#51, 4,
"explicit sync is used, but no acquire point is set")
Gdk-Message: Error 71 (Protocol error) dispatching to Wayland display.
An explicit-sync bug, not a GBM format/modifier one. Their test matrix
(RTX 3070, driver 615.71.09, webkit2gtk 2.52.6, KDE Wayland):
- __NV_DISABLE_EXPLICIT_SYNC=1 alone: clean, GPU (DMA-BUF) renderer, smooth;
- WEBKIT_DISABLE_DMABUF_RENDERER=1 alone on Wayland: clean (no X11 needed);
- WEBKIT_DMABUF_RENDERER_DISABLE_GBM=1: same explicit-sync error on Wayland,
"Failed to import DMABuf" under XWayland;
- X11/XWayland with the DMA-BUF renderer: "Failed to create GBM buffer".
New defaults when the NVIDIA driver is loaded:
- native Wayland: __NV_DISABLE_EXPLICIT_SYNC=1, GPU renderer kept;
- X11 session or user-forced GDK_BACKEND=x11: WEBKIT_DISABLE_DMABUF_RENDERER=1;
- never force X11 any more;
- LOTUS_GPU_SAFE_MODE=1: opt-in shared-memory rendering on Wayland too;
- LOTUS_NO_GPU_WORKAROUNDS=1 / user-set values: untouched.
One stderr line says what was set. 9 unit tests.

NVIDIA + Wayland (reported on CachyOS/KDE, driver 615.71, webkit2gtk
2.52.6): no window. GDK dies with "Error 71 (Protocol error) dispatching to
Wayland display"; forced onto XWayland, WebKit's DMA-BUF renderer then fails
with "Failed to create GBM buffer … Invalid argument". The reporter's
workaround, WEBKIT_DISABLE_DMABUF_RENDERER=1 GDK_BACKEND=x11, runs fine.
gpu_workarounds::apply(), first thing in main() (before GTK/WebKit init):
when the NVIDIA driver is loaded (/proc/driver/nvidia/version or
/sys/module/nvidia), set WEBKIT_DISABLE_DMABUF_RENDERER=1, and on a Wayland
session that has XWayland (DISPLAY set) also GDK_BACKEND=x11. Values the user
already set win; LOTUS_NO_GPU_WORKAROUNDS=1 turns it all off. Logs what it
set to stderr. Non-NVIDIA systems are untouched. Unit tests for the decision.
config.json: webAppUrl = https://chat.lotusguild.org, used by the web client
(cinny `calls-open-in-browser`) to send calls this WebKitGTK build can't make
to the web app in the browser.
