Review: Approved

The PR expands SignatureTest from 3 to 7 test methods with 27 assertions covering:

• All 9 primitive type signatures (testToSignaturePrimitives)
• Single/multi-dimensional and object arrays (testToSignatureArrays)
• Method signatures with various param/return combinations (testToSignatureMethod)
• Argument slot counting for 8 signature types (testGetArgSlotCount)

CoreTestSuite.java correctly adds SignatureTest.class to the suite.

Build verification passes (sh build.sh tests → 0 failures/errors). Tests follow JUnit 4 conventions and cover the Signature class comprehensively. Ready to merge.
