Description

What

The KBL2VEC converter did not produce any VEC Signals. This adds support for converting KBL connection signal information into a dedicated VEC signal list.

Changes

• New "Signal list" document — emits a standalone DocumentVersion (DocumentType=SignalList, DocumentNumber=Signals, DocumentVersion=1, De/En descriptions "Signalliste"/"Signal list") containing a single SignalSpecification. Company name comes from ConversionProperties.
• Signals from connections — one VecSignal per KblConnection with a non-blank Signal_name, using that name as both identification and signalName.
• Wire linking — WireElementReference.signal (single- and multi-core) is now linked to the signal of the wire's referenced connection.
• Deduplication — a post-processor collapses signals sharing a name into one canonical signal and repoints references, guaranteeing identification uniqueness within the SignalSpecification. It runs before XML-id assignment.

Design note

Signals are created 1:1 per connection (not deduplicated up front) so the KblConnection → VecSignal entity mapping stays unique and wire→signal linking resolves; duplicates are then merged in the post-processor.

New files

• transform/signal/SignalListDocumentVersionTransformer, SignalSpecificationTransformer, SignalTransformer
• post/SignalDeduplicationPostProcessor

Testing

• Unit tests for all three transformers and the dedup post-processor; updated both WireElementReferenceTransformer tests.
• End-to-end KblToVecConverterTest snapshot regenerated (all four samples now include the signal list); passes VEC schema validation, confirming all IDREFs resolve.
• Full module suite green (163 tests).

▎ ⚠️ Reviewer note: KblToVecConverterTest.snap is regenerated — the diff is large but mechanical (added SignalList document + references).
