build.yml: route 4 fourier-debian jobs to debian-aarch64 (bohr) (#47)

Closes task #134 work.

PR #44 showed the cross-distro ABI hazard for `libva-v4l2-request-fourier-debian`: building on Arch (libva 2.23) produced `__vaDriverInit_1_23`, which trixies libva 2.22 runtime cant bind. Same hazard applies to other fourier-debian jobs that link against debian-native libs.

**Moved from runs-on: arch-aarch64 → debian-aarch64:**
- ffmpeg-v4l2-request-debian
- mpv-fourier-debian
- daedalus-v4l2-debian
- daedalus-v4l2-dkms-debian

**Left alone (arch=all, no native compile against debian libs):**
- lmcp-debian
- claude-his-debian

Depends on PR #46 (label vs name fix) being merged so `debian-aarch64` actually routes to bohr.
