/**
 * Removal of DeepSeek DSML tool-call markup left in visible assistant text.
 *
 * DeepSeek models on OpenAI-compatible hosts sometimes emit their tool calls as
 * raw `<｜DSML｜…>` markup in `content`. A well-formed envelope is healed into a
 * structured call by `StreamMarkupHealing`, but a degraded model can drop the
 * opening `<｜DSML｜tool_calls>` / `<｜DSML｜invoke name="…">` tags (or the host
 * runs no healer at all). That markup must not stay in history: replaying it
 * teaches the model to keep writing tool calls as text (issue #10556). Callers
 * strip it before the message is committed and tell the model its call failed.
