ci: migrate primary CI jobs to ARM runners

thepastaclaw · thepastaclaw · commit cba08c0ca186 · 2026-03-17T13:31:05.000-05:00
Move depends-linux64 and its consumers (linux64, fuzz, sqlite, ubsan)
to ARM runners, making aarch64 the primary CI architecture. This
includes both build and test stages.

Drop the aarch64-linux cross-compile job (depends + src) and its
setup env script since we don't ship arm-linux-gnueabihf binaries
and now have native aarch64 coverage through the migrated jobs.

Jobs remaining on x86:
- nowallet (build + test): sole x86_64 native coverage
- mac, win64: cross-compile targets (x86 host)
- lint: architecture-independent

Update 00_setup_env_native_qt5.sh to dynamically detect HOST based
on the runner architecture instead of hardcoding x86_64.
