Merge remote-tracking branch 'origin/master' into jsonl-packed-chunk-rows

Conflict: master's docs-site rework (#e7b101a43) deleted the generated
website/zh-CN/api pages this branch had re-anchored after the last merge —
accept the deletions; the site now builds its API reference at build time.

`max-tokens` mirrors the model-call `FinishReason` of the same name: any `max-tokens` step in a turn makes the whole turn end `max-tokens` rather than `completed` (the cut-short fact wins over a later continuation), so a consumer can tell a clean stop from a truncated one — but only over `completed`: the `disposed`/`aborted`/`error` outcomes take precedence. `rejected` is a zero-step turn whose whole prompt batch an `agent/prompt-submit` hook blocked (the ACP bridge maps it to `cancelled`). `interrupted` is the one reason no loop emits — it is synthesized by crash recovery (see [persistence.md](persistence.md)). Both maps are merge-extensible.
