feat(core,cli): figma tokens import with alias-aware binding records (M2) (#1871)

tokensToVariables: variables -> composition brand-variable entries
(COLOR->hex/rgba, FLOAT/STRING/BOOLEAN), alias chains walked cycle-safe
to the leaf value while the binding keeps the semantic id. Sidecar
figma-tokens.json + .media/figma-bindings.jsonl records per spec 7.1.

hyperframes figma tokens: variables path, REQUIRES_ENTERPRISE degrades
to published-styles metadata (values resolve at component time).
