Add tests/cascade_cue.sx, a headless logic test that reuses audio.sx's pure cascade_cue_index / cascade_cue_name (the exact functions play_cascade calls) to lock the cascade-depth -> combo-cue clamp: depth <= 1 -> combo1, depth >= COMBO_CLIPS -> combo5, monotonic between. Covers the escalation logic the audio playback path can't gate-cover, with no audio. Committed stdout/exit snapshot; suite is now 19 tests.

// P10.4 — Cascade-cue selection snapshot: prove the cascade-depth → combo-cue
|
|
// mapping is a PURE, headless clamp. It reuses audio.sx's `cascade_cue_index`
|
|
// (and `cascade_cue_name`) UNCHANGED — the exact functions `play_cascade` calls
|
|
// — so the escalation logic the audio playback path can't gate-cover is covered
|
|
// here with no audio. The mapping clamps depth <= 1 to the first cue (combo1)
|
|
// and depth >= COMBO_CLIPS to the last (combo5), stepping up monotonically in
|
|
// between. The depth→index/name table below is locked by the committed snapshot.
