Updates the canonical Anthropic Opus model in every fallback chain (sisyphus, oracle, prometheus, metis, momus, visual-engineering, ultrabrain, deep, artistry, unspecified-high), the unspecified-high category default, the think-mode HIGH_VARIANT_MAP, the Claude Code alias map, the claude-thinking legacy alias, the context-limit GA regex, and event.ts fallback strings. Widens supportsCachedAnthropicLimit to accept both claude-*-4-6 and claude-*-4-7 so the 1M context cache still applies across the bump. Regenerates the bundled model-capabilities snapshot from models.dev and the model-fallback snapshot to match the new source output.
