📦 Ship relocatable QDMI bundles and native tools

Consolidated into #2715. Continue review and optimization there; the runtime packaging changes, simplifications, and measured size reductions are now part of one PR.

Description

Follow-up to #2715. QDMI device bundles can be copied with their worker, manifests, and declared assets without Core's private shared libraries. Wheels preserve the Python APIs and expose the QDMI C runtime and both native tools through find_package(mqt-core).

Three commits separate the work:

1. Use static native DD/common/configuration dependencies. Keep one private shared DD for Python DD/MLIR objects and compile only the two DD-facing adapters against it.
2. Split Runtime and Development installation/export sets. Add mqt-cc and MQT::mqt-cc alongside MQT::mqt-core-bench; keep C++ SDK targets source-only, with static MQT::CoreDD. An explicit Development request rejects a wheel installation.
3. Stage declared bundle files and remove recursive dependency discovery and the synthetic Windows target.

Windows import libraries remain included for public shared targets. Private Python support libraries stay unexported. macOS signing-aware installation is preserved. delvewheel --ignore-existing remains necessary to preserve bundled DLL names and locations used by CMake imports and standalone native tools; normal repair and filename controls do not provide an equivalent native installation layout.

Validation

• Native release: 3,983 passed, one skipped.
• Repaired manylinux ARM64 wheel: 1,938 Python tests passed, two skipped (optional QIR Runner and Python-version-specific Qiskit C API coverage). Includes DD/MLIR object exchange and relocated device loading.
• auditwheel repair and strict abi3audit passed. No LLVM/MLIR static archives or development export set in the wheel.
• External CMake consumer configured without LLVM/MLIR, linked the C driver, and ran both imported tools. Relocated DDSIM executed through its worker; SC loaded its configurations without Python startup.
• Source-installed static DD consumers compiled and ran with GCC 13 and Clang 23.
• Repository lint, the full executable documentation build against the repaired wheel, and generated documentation link checks passed. Hosted Windows/macOS qualification is pending. Packaging run was dispatched explicitly because the stacked PR change filter skipped packaging.

The repaired ARM64 wheel grows from 49.17 MiB to 66.21 MiB (+17.04 MiB); mqt-cc contributes 16.59 MiB compressed. The baseline ten-wheel set totals 370.75 MiB; the corresponding new total and other platform sizes await hosted artifacts.
