test(impact): re-baseline emit-persistence fingerprints for BasicBlock.callees

The new `BasicBlock.callees` column changes the BasicBlock node CSV header (and
thus the byte-identity fingerprint over all emitted CSV lines), tripping the
emit-persistence --check gate that the CI benchmarks job runs. This is the gate
working as designed — a legitimate, reviewed emit change.

Regenerate both committed baselines (whole-graph + streaming PdgEmitSink) per the
documented procedure. The streaming gate still confirms byte_identical_nodes/edges
and resident_basic_blocks === 0, so the schema change preserves the streaming
invariants.

Byte-identity gate for #2203 U2/U3. NOTE: a future change that legitimately reorders emit (without changing the node/edge SET) will trip --check; regenerate then. scaling_budget bounds (t_large/t_small)/(LARGE/SMALL): observed ~0.95-1.05 (linear); 1.8 tolerates disk-I/O timing noise on CI while still catching an O(n^2) re-regression (~4x). max_ms_large=1000ms is a coarse absolute backstop (observed ~200ms) that catches a gross uniform slowdown the ratio gate misses; generous so CI host noise won't flake it.
