Intel Arc 140V (Lunar Lake): walls missing inside Link's house; earlier device-lost crashes fixed by foliage-linux-updater #374

This is what Claude told me to post.

**Hardware / build**
- Lenovo Yoga Slim 7 15ILL9, Intel Core Ultra 7 258V, Intel Arc 140V (integrated, 16 GB shared), 32 GB RAM
- Intel driver 32.0.101.9150, Windows 11
- Build: foliage-linux-updater (log line 1 confirms latest)
- hookshot_env.txt: `RX_VK_ASTC_CPU=1` only
- Options: Handheld profile On, Resolution 67%, Upscaling Lanczos

**What works now (thanks!)**
- On less-stutter I had device lost at the title menu (fixed by robust, now default) and in a compute dispatch in the Deku Tree area (`4b03b3040d7cf076`). On foliage-linux-updater, with the 32-lane pin on, no device lost in Kokiri.
- Foliage draws. About 25 fps walking with Handheld profile On (10–15 fps without it; GPU time 60–96 ms/frame with ~4,500 draws).

**Problem: inside Link's house, walls/floor/ceiling are missing; the forest shows through (screenshot attached)**
- 0 skipped draws in gameplay, and the only failed programs are the 10 networks (expected on this card).
- Four mesh programs get an unbound storage buffer at stage 7, c5+0x60, every time: addr 0x10001c10a, size 0x3f800000 (that's 1.0f, so it looks like a float read as a pointer/size):
  `68642bb810ee3e7c`, `6b4dea601798c255`, `739acd678ae08655`, `d905f52b7517c681`
- Not sure whether this is Intel-only or happens on NVIDIA too.

**Other notes**
- GPU ASTC decode left blocky corruption on the title logo on less-stutter; I've used `RX_VK_ASTC_CPU=1` since (Deku Tree's 1365x1365x90 ASTC arrays take ~6 s each that way). Haven't retested GPU decode on this build.
- With the TAAU network stood in (no coop matrix), I'd expect some dithered transparency to show; separate from the missing walls.

Happy to test switches or builds.
