[codex] Add analysis graph hooks for ndarray features

[colonelpanic8]

Summary

• Adds optional analysis graph hooks to ndarray global and per-player feature adders.
• Lets NDArrayCollector build and evaluate one shared analysis graph from the union of feature-adder dependencies.
• Reuses analysis frame input bookkeeping between the analysis collector and ndarray runtime.
• Adds a regression test proving two ndarray adders share one graph evaluation per emitted row.

Validation

• cargo test analysis_feature_adders_share_one_graph_evaluation_per_ndarray_row
• cargo test --lib
• cargo test currently hits a pre-existing tests/stats_frame_resolution_test.rs failure: events.boost_pickups.len: left=0, right=557; reproduced on clean origin/master.
