Add TDE 1.1 cross-language complexity parity - #151

What changed

• Adds the TDE 1.1 cross-language complexity-parity architecture decision and support matrix.
• Retains Radon for Python and adds the pinned public Lizard route for TypeScript/JavaScript, Swift, C/C++, and C#.
• Normalizes primary-product-language complexity through the existing capability, policy, evidence, and qualification path.
• Introduces shared source classification so coverage output, generated files, dependencies, build output and verification material do not affect Code Size or Complexity metrics.
• Makes analyzer discovery find scripts installed with the active public wheel even when its bin directory is absent from PATH.

Why

TDE 1.0.5 only produced meaningful complexity evidence for Python. The selected seven DJConnect source consumers need one auditable, primary-language route without consumer-local analyzers or policy forks.

Validation

• PYTHONPATH=src python -m unittest discover -s tests -q
• Exact isolated wheel installation with public tde CLI assessment for TypeScript, Swift, C++, and C# fixtures.
• Verified canonical complexity.cyclomatic.product.maximum output and analyzer provenance.

Governance

No thresholds changed. No consumer workflow, required check, merge policy, soft-fail behaviour, or product source was modified. Consumer integration and public release remain follow-up work after this draft is reviewed and qualified.
