feat(tide-table): CLAP emotion ontology — synonym clusters on the V/A circumplex

Each emotion is a CLUSTER of angle prompts (adjective pairs + scene metaphors +
bodily framings, EN+FR) marginalized to one robust per-emotion score (mean cosine,
size-invariant) — the synonym→emotion fold mirrors the resolver's descriptor→family.
12 emotions × 6 angles, each placed on Russell's valence/arousal circumplex, so the
distribution yields a continuous V/A point + a discrete top-emotion label.

Per-window kernel: score(ae_row) takes one CLAP audio embed → {scores, dist, top,
valence, arousal, confidence}. Validated: probe archetypes land correctly (melancholic
0.76, aggressive 0.94, hypnotic 0.94, cold 0.72); real-audio path confirmed (pad→
dreamy/melancholic calm). Feeds the planned per-track emotion timeline (hexa lane).
