Fix: Schema version race condition causing Node 3 instability
Prevent nodes from becoming ALIVE before their schema versions catch up
with peers. This fixes a race condition where anti-entropy could sync
from behind peers, causing DDL loss and node instability.
Defense-in-depth approach:
- Promotion criteria now blocks JOINING→ALIVE when local schema < peer
- Anti-entropy skips peers with older schema versions
- Fresh databases (schema=0) are now properly compared
