Dynamic switch table (B2) -- FABRIC-3.6.md task 3.1

Browse Source

Replaces the fixed SK_SWITCH_MAX_SLOTS=16 compile-time array with a
boot-time, RAM-derived allocation via a new sk_vm_switch_signal_boot_init(),
kmalloc'd to stadium_max_vm_count() entries -- the same pattern
session_boot_init() already established for Stadium-derived sizing.
Every switch-signal participant is a Stadium VM, so this reuses that
bound directly rather than deriving a separate one.

Verified live on all three architectures: switch table sized to 50
slots (amd64), 202 slots (aarch64), 50 slots (riscv64) -- all well
past the old fixed cap. All three boot to [zuse@Hera] ok> cleanly;
dict_hash for Hermes/Hestia identical across architectures, unmoved
from pre-task values.
