Problem: Dead instances pile up indefinitely. Failed metadata parsing leaves stale data in registry. No cleanup mechanism exists.
Changes:
1. Remove instance from registry on parse failure (corrupted metadata = unrecoverable)
2. Evict instances with state="DEAD" on next health check (was only evicting by heartbeat age)
This prevents:
- Memory leak from accumulating dead/corrupted instances
- Stale data persisting after parse failures
- Dead instances blocking resources indefinitely
