Detailed Description

Domain objects representing Wilson coefficients and their matching metadata.

This header provides:

MatchingInfo: a small aggregate describing how to compute a coefficient at a given QCD order, and which source parameters it depends on.
WilsonCoefficient: an abstract base class representing one Wilson coefficient, with:
- a name,
- a contribution type (SM/BSM/…),
- a storage block name where values are stored in the Parameters system,
- per-order matching metadata (sources, compute function, LHA id).

The class is designed to interact with the framework layers:

It can reference values in a Parameters scope through IParameterProxy (typically a ParameterProxy configured with ParameterType::WILSON).
It can be used with the dependency system: each (order -> MatchingInfo) stores the set of ParamId sources that should trigger updates.

Conventions used:

QCD orders are represented by QCDOrder (LO/NLO/NNLO).
Contribution types are represented by ContributionType (SM/BSM/…).
LHA identifiers are stored as LhaID and follow the mapping conventions of WCoefMapper.
