xfy 9b8ce2a08a fix(config): real circular include detection with visited set
Replace depth-only detection with path-based visited set tracking.
Detects cycles immediately on first revisit instead of after 10 depth
iterations. Supports diamond patterns (A->B->shared, A->C->shared)
via backtracking. Add self-include and diamond tests. Document that
only servers/stream/variables are merged in defaults.go.
