+/**
+ * Think Mode Switcher
+ *
+ * This module handles "thinking mode" activation for reasoning-capable models.
+ * When a user includes "think" keywords in their prompt, models are upgraded to
+ * their high-reasoning variants with extended thinking budgets.
+ *
+ * PROVIDER ALIASING:
+ * GitHub Copilot acts as a proxy provider that routes to underlying providers
+ * (Anthropic, Google, OpenAI). We resolve the proxy to the actual provider
+ * based on model name patterns, allowing GitHub Copilot to inherit thinking
+ * configurations without duplication.
+ *
+ * NORMALIZATION:
+ * Model IDs are normalized (dots → hyphens in version numbers) to handle API
+ * inconsistencies defensively while maintaining backwards compatibility.
