docs(stake): correct the MOR routing comment in use-morpheus-stake (#257)

The header claimed the claim flow and the "opt-in donate split" would "come in
a later phase". Both statements are false and have been for a while: the claim
flow ships in MorLootbox / RewardClaimModal, and `stake()` 250 lines below wires
the split by DEFAULT — a second signature pointing this pool's claim receiver at
the staker's deterministic 3-way PushSplit (staker 50 / Gnars 25 / athlete 25).

Replaces it with what the file does, including the part that is easy to miss:
that second signature is the entire opt-out, and it is silent. It sits in a
try/catch, so declining it leaves the receiver at 0x0 and the staker keeps 100%
of the MOR while the stake still stands. Anyone tempted to "fix" that swallowed
catch should know stake-graph.ts reads a zero receiver as a raw deposit rather
than a sponsorship, and deliberately excludes it from the orbit and its totals.

Comment only — no behaviour change, no user-facing copy touched.
