Adds SkHermesChannel: a channel is an index into a boot-time, stadium_max_vm_count()-sized table (same sizing pattern task 3.1 established for the switch table -- no separate numeric rule was ruled for this table, so task 3.1's bound is extended directly, flagged as such rather than restated as a new ruling). No name field, mirroring messaging.4th's own nameless CH-ARENA. The common channel (index 0) is created at boot and permanent. Hera subscribes explicitly in kernel_main.c (she is the one VM never born through capsule_birth_baby()); every other VM -- Tripod fleet and future WIREBIND identities alike -- subscribes inside capsule_birth_baby() itself, the single choke point every other birth already passes through. Inert: no publish, no dispatch, no ACK/NACK, no ACL hook (tasks 3.3, 3.6, 3.7). Verified live on all three architectures: channel table sized to 50/202/50 slots (matching switch-signal's own per-arch sizing), common-channel fleet self-test confirms all four Tripod members are members, and a synthetic create/subscribe/unsubscribe/ destroy round-trip against a private topic passes, including refusing to destroy the common channel.
