refactor(models): bump claude-opus-4-6 to claude-opus-4-7 across fallback chains, categories, and hooks

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.
