Remove prescriptions of specific execution tools (CLI, REST/curl, --limit/--page, sleep-based rate limiting, base64 auth) from the error-analysis reference so it describes what the agent should do rather than how. Clarify the critical rule to perform Langfuse-instance interactions directly while still pausing for user judgment. Bump plugin manifests to 1.1.1.

- Setting up Langfuse tracing in a project
- Setting up CI/CD experiment gates with
langfuse/experiment-action - Auditing existing instrumentation
- Migrating prompts to Langfuse prompt management
- Querying traces, prompts, or datasets via the API
- Looking up Langfuse docs, SDK usage, or integration guides
