Detailed Description

Test-only fixture that owns the storage backing a NodeContext.

NodeContext holds non-owning references to a feature matrix, group partition, and outcome vector, so a test must keep those alive separately. This fixture bundles them with an RNG and a fully-wired NodeContext, so each strategy NVI test can stop redeclaring the boilerplate.

Three constructors:

• (x, GroupIdVector ids) — classification flavour. y_vec is derived from ids via cast<Outcome>(); the partition is GroupPartition(ids).
• (x, OutcomeVector y_vec) — regression flavour. y_ids and the partition are a median split matching ByCutpoint::init's behaviour at the root, so tests pass only the continuous response they actually care about.
• (x, GroupPartition, OutcomeVector y_vec) — escape hatch for tests that need a partition shape neither default produces (e.g. gp.subset(...), custom two_groups(...) bounds). y_ids is left empty in this case since the partition came in pre-built.

Public fields so tests can mutate them after construction (e.g. f.x = …, f.ctx.projector = …).

Non-copyable / non-movable: ctx references the other members of the same fixture, so any copy or move would silently produce dangling references.
