✨ Add missing TKET decomposition and placement passes

[flowerthrower]

🤖 AI text below 🤖

Description

Adds the TKET actions used by the paper prototype but missing from the production action registry:

• optimization: KAKDecomposition(allow_swaps=False)
• layout: GraphPlacement
• layout: NoiseAwarePlacement

TKET placement maps are translated to Qiskit layouts and materialized with the existing Qiskit layout passes so the environment retains a complete TranspileLayout. TKET layout and routing actions are masked for circuits containing operations wider than two qubits, matching the prototype limitation.

This draft is stacked on #779. It intentionally contains only the raw action support; documentation and new tests are deferred.

Validation

• repository lint, including ty
• focused KAK optimization invariant test
• direct GraphPlacement and NoiseAwarePlacement layout smokes
• direct wide-operation mask and global-calibration-entry smokes

Checklist

• The pull request only contains focused changes required for this feature.
• New tests and documentation are intentionally deferred while the feature stack is assembled.
• I reviewed the complete base-to-head diff.
