starkernel: item 4.1a -- quota granting, Hermes's one-time birth grant

Punch list §25 item 4.1a complete.
New prerequisite item, found while scoping 4.2: no quota-granting mechanism
existed at all. Adds stadium_grant_quota(new_vm_id, from_vm_id) -- a
one-time initial grant at birth, distinct from item 1.3's still-unbuilt
recurring capacity-transfer arbitration. Splits the donor's free list evenly
by cell count, reassigns stadium_owner[] for every moved cell, and grants
the new VM a fresh Q48_ONE reservoir (not a split of the donor's -- per-VM
conservation, same pattern as Hera's own boot grant). Wired into every baby
VM's birth in capsule_birth.c.

Verified via a boot-time self-test in kernel_main.c using a synthetic
identity (not the real UUID pool, not a real capsule birth -- item 0.1's
Hera-alone pruning stays intact). All three architectures booted to ok> with
identical output: grant OK, Hera reservoir=0 (already fully committed to
resident words, correctly unchanged), test-vm reservoir=65536 (fresh
Q48_ONE). dict_hash identical across all three and unchanged from item 4.1's
baseline (0x3d4e1daf289da94f) -- confirms no dictionary word was added.

* residents (including a pinned cell 0, if from_vm_id is Hera) are
* unaffected. Grants new_vm_id a fresh Q48_ONE reservoir -- NOT a fraction of
