feat(raft-drive-async): add drive-async config constants + liveness-reservation helper (task 1.1)

Browse source 
drive_async_liveness_reserved = max(1, min(n_peers-1, n_vcpus-1)) — single
source of truth for VTASK_LIVENESS_RESERVED (deadlock-freedom floor applied
last). New DEFAULT_CONNECT_TIMEOUT_MS / DEFAULT_SLOWLANE_* constants. Resolved
reservation logged at init; under-provisioned (n_vcpus<n_peers) clamp WARNs
loudly, never self-terminates. 8 unit cases, mutation-verified.
