Add Experimental GeForce NOW support - #5
Conversation
Share form encoding between authentication clients and retain the form bounds checks.
Add device sign-in, saved credentials, library browsing, queue handling, and WebRTC streaming with the existing hardware decoders. Add service selection, provider badges, and mouse controls for game launchers. Cover protocol parsing, expiry, refresh, and cancellation with host tests.

Inline comments:
In `@packaging/portmaster/greenovercast/port.json`:
- Around line 16-17: Update the inst and inst_md metadata strings to state the
required service entitlements: Xbox cloud gaming requires a Game Pass plan with
cloud gaming, while GeForce NOW requires membership plus access to the game.
In `@src/provider/geforce_now/auth_client.zig`:
- Around line 6-11: Update the bootstrap/test setup around tools/bootstrap.sh
and tools/build-dependencies.sh so SDL2 and its required headers are built
before tools/zig.sh build test runs. Invoke tools/build-dependencies.sh after
bootstrap, or have bootstrap invoke it, while preserving the existing
.tools/deps/aarch64-linux-gnu/include path and avoiding additional include paths
or unrelated host SDL2 installation.
In `@src/provider/geforce_now/webrtc_session.zig`:
- Around line 355-371: Update Session’s waitForOffer to retain pre-offer .ice
messages via a dedicated early-candidate collection instead of discarding them;
initialize and free that collection in the Session lifecycle, including destroy.
In setup, immediately after rtcSetRemoteDescription succeeds, drain the buffered
candidates through the same TCP filtering and sdp_mid handling used by
handleSignaling, then continue normal signaling.
In `@src/ui/handheld_ui.zig`:
- Around line 86-89: Update the event handling branch so `ui.quit_requested` is
set only for `SDL_QUIT`; handle keyboard Escape separately by setting
`ui.cancelled` and returning success, matching controller B behavior without
marking the application for termination.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Replace unsupported tracking macros with a sentinel instead of failing.
expand returns error.UnsupportedTrackingMacro for any [ that does not start one of seven known macros. Tracking URLs from VAST ads often contain other macros. Examples are [ASSETURI], [ADSERVINGID], [DEVICEUA], [PLAYERSTATE] and [BREAKPOSITION].
The error reaches the playback flow through beacon in ad_playback.zig:
- Impressions (Line 307), icon views (Line 313) and tracks (Line 319) all use
try beacon(...). One unknown macro in a tracking URL makesplayfail. runthen sends error beacons at Line 130. Error URLs with the same kind of macro fail in that catch block too, and the new error replaces the original one.executereturns the error for every non-no-fill case. A Free-tier ad with a third-party tracker can fail because of one tracking pixel.
Tracking URLs are fire-and-forget. A macro the player does not support must not stop playback. IAB macro guidance tells players to put a placeholder value in unknown macros (for example -1). Apply that to any [A-Z0-9_]+ token. Copy a [ that does not start a token as a literal byte.

Handle malformed ad metadata without aborting session polling.
ad_protocol.parse can return errors for malformed sessionAds. The try in parseSession propagates those errors, and waitUntilReady propagates the parseSession error during its next poll. One malformed ad response can therefore terminate the session instead of continuing to poll. If malformed ad metadata is non-fatal, handle it with the defined fallback while still propagating allocation failures.
Moving the call outside the return literal is not required for cleanup. The active errdefer handlers already release id, media_ip, signaling_url, and ice_servers when the return expression fails.

Review comment at @src/provider/geforce_now/cloudmatch_protocol.zig at line 377:
Update parseSession’s ad_protocol.parse handling so malformed sessionAds use the
defined fallback instead of propagating an error and aborting polling, while
allocation failures still propagate. Keep the existing return-expression
structure and active errdefer cleanup unchanged.

failures do not stop subsequent error URLs, and drain is attempted even if
reporting fails. Ignore reporting and drain errors there, then return the
original playback error.

- Around line 199-201: Update selectAds to order pod ads by their VAST sequence
rather than manifest order. In the playback test, give each ad a distinct media
URL, record media fetch order, and assert sequence 1 is fetched before sequence
2.

What does this change?
Adds GeForce NOW alongside Xbox Cloud Gaming, with saved sign-in, library browsing, queue handling and hardware-decoded streaming. Choose a service at startup or switch from Settings without closing the app.
Includes mouse controls for store dialogs and launchers, service icons in the library, and an updated search keyboard. Also fixes Cedar decoding and authentication issues found during testing.
How did you test it?
GFN playback tested on RG35XX-H (muOS), RG40XX-H (Knulli), Miyoo Flip (SpruceOS) and R36S (dArkOS).
Host tests, formatting checks, the ARM64 build and ABI smoke build pass. Device testing was not repeated after the final review fixes.
R36S frame pacing still needs work. GFN testing on ROCKNIX and AmberELEC is still pending.
Summary by cubic
Adds experimental GeForce NOW support alongside Xbox Cloud Gaming, letting you choose a service at startup or switch in Settings without closing the app. Also plays the Free tier's ads natively.
