Re-structure the Lightning-Base class and core src files

1

**Context:** :warning: We will merge this after the v0.41.0 release - Remove dispensable C++ source code in Lightning wheels. - Re-structure the Lightning-Base class **Benefits:** - Cleaner wheels src code...

#### Issue description Simulating `qml.templates.GroverOperator` with Lightning-Kokkos could not be scaled similar to Lighnting-Qubit. The following code will be killed due to memory segfaults: ```python import pennylane as qml num_wires...

Parallelize the perturbation theory error

4

**Context:** Add 3 parallel modes to `perturbation_error`: - "state" parallelizes the computation of expectation values per state, - "commutator" parallelizes the application of commutators to each state. - "nested_commutator" parallelizes...

A graph-based decomposition xDSL pass

1

**Context:** The first prototype of a decomposition xDSL pass for the graph-based decomposition system [sc-92672]

Enable OpenMP pragmas for gate kernels on Linux Wheels

For context, the default threading behavior of lightning.qubit assumes single-threaded execution at the gate level, while allowing multi-threaded execution over observables when using the adjoint differentiation pipeline. This design ensures...

**Context:** Prototype PL's [DecompositionGraph](https://github.com/PennyLaneAI/pennylane/blob/f818dc209742602b20e9a05472af35ed45dd0929/pennylane/decomposition/decomposition_graph.py#L131) in C++ for integration with the Catalyst core compiler **Benefits:** - Construct and solve the decomposition graph in MLIR instead of Python - Avoid Python/JAX overheads...
