The "Proof Size Constants" section listed the C++/Noir/TS constant updates
needed when proof lengths change but didn't mention that the committed
Prover.toml fixtures (which carry hardcoded proof arrays) also need
regenerating. Without the regen, `nargo execute --program-dir <crate>`
fails type-checking on every protocol circuit using ChonkProofData.
Adds a "Prover.toml Fixtures" subsection covering:
- the symptom (Type Array length mismatch in nargo execute)
- the regen command (AZTEC_GENERATE_TEST_DATA=1 FAKE_PROOFS=1 ... full.test)
- the FAKE_PROOFS=1 flag that keeps the run to ~2 min
- the supplementary orchestrator_single_checkpoint test for circuits
not exercised by full.test.ts
- how to verify (nargo execute should print "Circuit witness successfully solved")
