refactor(telemetry): remove the OTel backend's flush forwarding

Three review rounds each found a new silent-loss path in the same
wrapper state (dispose racing an in-flight flush, overlapping hints
displacing the retained promise, the provider's fixed 30s flush timeout
rejecting while the processor still drains). Every path exists only
because forwarding the seam's turn-boundary hint to forceFlush() made
this backend the process's second flusher against undocumented SDK
internals from the upstream experimental tree.

The backend now implements no flush(): the batch processor is the only
flusher, its scheduledDelayMillis (already deployment-tunable through
the processor passthrough) governs export cadence, and shutdown()'s
drain is complete by construction. The two race-pin tests collapse into
one dispose-during-in-flight-batch drain pin; the seam's optional
flush() contract now tells implementers they own the concurrent-flush/
shutdown interaction. Removal rationale and the reinstatement trigger
(a stated turn-boundary latency requirement scheduledDelayMillis cannot
meet — and then via the processor's own forceFlush(), never the
provider's timeout-wrapped one) are recorded in the revival Agent Note,
both languages.

`exporter.url` 是本包唯一自行校验的字段:必填、无默认值、必须能解析为 `http(s)`,因此缺失端点会在插件加载时失败。其余全部是 SDK 自己的选项形态,由 SDK 拥有并在 SDK 文档中说明,两个配置块都整体透传(passthrough):`OTLPExporterNodeConfigBase` 的每个字段(`headers`、`timeoutMillis`、`compression`、`keepAlive` 等)都会到达导出器;批处理、重试、队列上限,以及持续失败下的丢失策略,都是 SDK 的文档化行为,经 `processor` 透传调优。从 `cordis.yml` 中删除该配置块即为退出方式:无残留状态,也没有 `enabled` 开关。
