Remove Claude subscription-based model adjustment

[juliusmarminge]

Summary

• Remove the subscription-driven model adjustment logic from ClaudeProvider.
• Return the provider's model list unchanged during Claude status checks.
• Delete the unused premium subscription normalization and 1M-default flipping code.

Testing

• Not run (PR description only).
• Verify Claude provider status responses still include the expected model list shape.
• Confirm the default model behavior now comes solely from the upstream/provider-provided metadata.

Note

Medium Risk
Changes Claude provider status responses to stop rewriting model capability defaults based on detected subscription, which may alter default context window selection for some users. Risk is limited to provider metadata/UX, with no auth or data handling changes.

Overview
Removes the subscription-tier driven model adjustment in ClaudeProvider that previously promoted the 1m context window option to default for premium plans.

checkClaudeProviderStatus now always returns the models list from settings/built-ins unchanged (while still detecting subscription/auth method for metadata), simplifying behavior and making defaults come solely from the provider model definitions.

Note

Remove subscription-based default context window adjustment from ClaudeProvider

Removes adjustModelsForSubscription and PREMIUM_SUBSCRIPTION_TYPES from ClaudeProvider.ts. The provider now returns the base models array unchanged for all subscription types. Behavioral Change: premium subscribers no longer have the 1M context window set as the default option.
