API-success telemetry now emits a separate tengu_tool_schema_sizes event that breaks down tool schema character lengths by category (static, mcp_tool, skill_tool, other), deduplicated and capped at 512 distinct hashes. The existing tengu_api_success event also gains a new requestPrefixTelemetry block.
