Artemis bus-agnostic discovery: signature format + idle-loop generalization (FABRIC-3.md §XXVI follow-on)
Step 1: new artemis_sig_t header format (magic 'ARTM', sibling to homeblocks_sig_t, distinct so a generic scan can tell Artemis's own disk apart from an identity thumbdrive by content alone) -- artemis_sig.h/.c, wired into Makefile.starkernel. Step 2: sk_repl_idle()'s existing per-USB-MSC-slot attach handling (the pattern WIREBIND already uses for identity thumbdrives) now also checks for the ARTM signature whenever a device's home-blocks check comes back BLANK. On a match, once Artemis's own storage-attach round-trip (HERA-BLK-ATTACH-REQ/BLK-ATTACH-ACK) confirms success, capsule_zuse_boot_load_root_pubkey() runs -- the same call kernel_main.c's synchronous QEMU-only virtio-blk path already makes, now reachable without a hardcoded PCI vendor/device scan. That function is already idempotent (no-op once zuse_root_pubkey_known is set), so no boot restructuring was needed despite the initial concern that deferring Artemis discovery to the idle loop would require one. Verified: clean build + QEMU boot to [zuse@Hera] ok> on all three architectures, zero regression to the existing virtio-blk/Zuse-thumbdrive attach path. Steps 3 (genesis-stamping onto disk/artemis.img) and 4 (growable production log-persistence region) not yet started.
