Browser-based OAuth flow using Anthropic's hosted callback. Users authorize on claude.ai, paste the code back, and tokens are encrypted and stored in D1. Includes auto-refresh, Bearer auth via custom fetch wrapper, and mcp_ tool name prefixing required by the OAuth endpoint. Also fixes provider-config save bug that required encryption key unconditionally — now only checks when API key is present.
