feat: SAS-R0 boot-time capability attestation - unimplemented feature blocks boot

- attest.c: subsystems report readiness, attest_check() before DSK handoff

- FUCK [attest] require_<name>=1 (default) + not-ready -> lotus panic with feature errcode

- wired: sealed_mem/pckc/sched/drr/fs_fat32_rw/net_wired + placeholders (pkg/brand/dkm/nvme/virtio/wlan/vmx/drr_real_mac)

- negative test: require_pkg=1 -> boot-time PKG-E10 panic (verified); dev/release FUCK whitelist = STATUS.md undone items

- CLAUDE.md whitelist rule updated
