V20 (pre-release): Real-time presenting toggle

Pre-release: source code only. No IPA and nothing from the game are attached or in the repository. Build your own from your own dump of the game (the v1 dump: base game + update v131072) with the steps in docs/games/kid-with-sword-remake.md, with an env file holding the lines under "Build settings" below.

The Legend of Zelda: Ocarina of Time (Switch 2) as a native iPhone and Mac app, on top of nxnative.

In this build (V20)

• Real-time presenting (launcher, Performance, on by default): on tells iOS how much of each frame the presenting thread needs, which keeps it fast; off may use less power, with a risk of more stutter. For comparing power on the phone.
• The GPU profile keeps one frame in 600 without the per-dispatch timing.
• Includes V18 and V19.

Build settings

DM_UPSCALER=metalfx

Status

• Tested on an iPhone 18 Pro with the toggle on (render scale 0.60, 60 fps).
• Known: the game closes at the first ocarina note (Impa, Zelda's Lullaby), which blocks the main quest. Fixed in nxnative main; the fix is not in this build yet.
• Keep at least 15 GB free on the phone: the game stops itself under 5 GB free.
• At 60 fps the phone heats up within one to two minutes and iOS lowers the clocks; 30 fps holds for long sessions.
