<type>(optional scope): <description>More detailed description
en:
Adds
callbacks/tls, an opt-in Eino callback module that exports callback spans to Volcengine TLS. It keeps existing callback and generic OTLP behavior unchanged unless TLS export is explicitly configured.The module records
agent.turn,llm.request, andtool.callspans, aggregates streaming chunks before exporting, and attaches token usage, provider/model metadata, tool arguments/results, error state, and duration when available.The PR also adds TLS transport options in
libs/acl/opentelemetryand Ark callback usage metadata needed for complete trace attribution.The module-local
genprotoreplacement was removed so downstream consumers do not rely on non-transitive Go module configuration.zh(optional):
新增可选的
callbacks/tls回调模块，将 Eino 回调 Span 导出到 Volcengine TLS；未显式配置时不会改变现有 callback 或通用 OTLP 行为。流式输出会在导出前聚合，并保留模型、Token、工具调用、错误和耗时信息。Which issue(s) this PR fixes
