Bundled offline pricing data missing claude-opus-4-6

[hbthegreat]

Description

The bundled offline pricing data (baked in at build time for v18.0.5) doesn't include claude-opus-4-6, which is now the latest Opus model used by Claude Code.

LiteLLM's upstream model_prices_and_context_window.json already has claude-opus-4-6 entries, so this just needs a rebuild and publish to pick up the latest data.

Impact

• ccusage statusline defaults to --offline mode, so it uses the stale bundled data
• Any session using claude-opus-4-6 shows incorrect/missing pricing
• Workaround of --no-offline works but adds a network call per invocation

Expected fix

Rebuild and publish a new release — no code changes needed, just refreshing the prefetched pricing dataset.
