- Around line 42-43: Add a Doxygen comment above the public factory declaration
createNativeGateSynthesisPass describing its purpose (what the pass does),
documenting the parameter `@param` options (type NativeGateSynthesisOptions) and
any important semantics of those options, and the return value via `@return` (a
std::unique_ptr<Pass> owning the created pass). Keep wording consistent with
surrounding pass factory comments (brief one-line summary plus `@param/`@return
tags) and place it immediately above the declaration for
createNativeGateSynthesisPass.

…1672) ## Description - Consolidate Euler decomposition into `Euler.h` / `Euler.cpp` (angle extraction + `synthesizeUnitary1QEuler` IR emission), replacing the previous `EulerDecomposition` / `GateSequence` / `Helpers` / `UnitaryMatrices` split. - Add the `fuse-single-qubit-unitary-runs` MLIR pass: fuse maximal runs of constant single-qubit unitaries on a wire by composing 2×2 matrices and resynthesizing in a configurable Euler basis (`zyz`, `zxz`, `xzx`, `xyx`, `u`, `zsxx`), with `gphase` for exact global phase. Split up and refactored from #1665. ## AI Assistance Used Composer via Cursor for parts of this change.

Description
Introduces a
native-gate-synthesistransform on QCO modules that lowers arbitrary supported unitaries to a comma-separated native gate menu, with scoring over two-qubit count, single-qubit count, and local depth.User-visible behavior
--native-gates=<menu>onmqt-cc(empty menu = no-op), aligned with pass options documented inPasses.td(native-gates,score-weight-twoq,score-weight-oneq,score-weight-depth).Fixes #(issue)
