Problem
The daemon cannot build on x86_64 dev machines because bpf_loader.c includes generated skeleton headers (owlbear_lsm.skel.h, owlbear_trace.skel.h, owlbear_kprobe.skel.h, owlbear_net.skel.h) that only exist after make -C ebpf on an ARM64 host with clang + bpftool.
This means the full daemon binary is unbuildable outside the Graviton3 instance. Unit tests work because bpf_event_convert.c was extracted, but you can't even compile-check main.c or bpf_loader.c locally.
Proposal
Generate stub skeleton headers (empty struct + no-op open/load/attach/destroy functions) that satisfy the compiler on non-ARM64 hosts. Gate via #ifdef __aarch64__ or a BPF_STUBS=1 make variable.
This unblocks make daemon on dev machines for syntax/type checking and local iteration.
Acceptance
make daemon BPF_STUBS=1 compiles on x86_64 with -Werror- Real skeletons still used on ARM64 builds
