Align the Claude Sonnet 4.6 context-window contract.

src/providers/registry.ts:217 sets claude-sonnet-4-6 to 1_000_000, while scripts/generate-jawcode-metadata.ts:30-32 intentionally overrides both generated IDs to 200_000. The catalog merge therefore uses 200_000, but direct provider configuration uses 1_000_000. Choose one supported limit and align the registry, generator override, and related tests. Do not add a [1m] variant unless the Anthropic registry exposes and routes that ID.

In `@src/providers/registry.ts` at line 217, Align the Claude Sonnet 4.6
context-window limit across ANTHROPIC_MODEL_CONTEXT_WINDOWS, the overrides in
generate-jawcode-metadata.ts, and related tests by choosing one supported value.
Keep claude-sonnet-4-6 consistent between catalog generation and direct provider
configuration, and do not add a [1m] variant unless the Anthropic registry
exposes and routes that model ID.
