/// <summary>
/// Represents the capabilities of an AI model.
/// </summary>
/// <remarks>
/// A set of capabilities is one value, not a collection: a model profile carries this enum as a
/// single field, and asking whether a capability is present is one bit test instead of a walk
/// through a list. That is why the members are powers of two.
///
/// The numeric values are an implementation detail and are never written anywhere. Overrides,
/// plugins, and the settings file all address a capability by its name, so the names are the part
/// which must not change. Removing a member would silently drop the override an organization wrote
/// for it, which is why the members we no longer hand out ourselves are still here.
///
/// Adding a member means adding the next free bit. Sixty-four of them fit; should they ever run
/// out, the answer is a second enum next to this one rather than a wider underlying type, because
/// widening changes the meaning of every value already written down.
/// </remarks>
