Bridge auf direkte Anthropic API umgebaut — ~2s statt 5-10min
- @anthropic-ai/sdk statt Claude CLI — kein Hook/MCP/Plugin-Overhead - OAuth-Token automatisch aus ~/.claude/.credentials.json geladen - Streaming via messages.stream() — Text erscheint sofort - Conversation-History für Multi-Turn (clear-history Befehl) - AbortController für sofortigen STOPP - Kosten-Berechnung pro Request - API-Key auch per set-api-key Befehl oder ANTHROPIC_API_KEY Env-Var Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
