Sækja hellogrok-cli 0.1.30

Added
- Closed-Responses-schema negotiation for hosted web search. The standard web_search_call.action.sources include hint remains the default for compliant providers. Volcengine Ark (*.volces.com) — whose include is a closed enum rejecting unknown values with InvalidParameter, and whose tool schema rejects unknown declaration fields such as filters and the allowed_tools selector — is handled ahead of time: the hint is omitted and the hosted-search declaration is sanitized to the documented field set, with a pure hosted-search allowed_tools selection collapsed to required. Any other upstream that proves its schema closed with a 400 (include or tool-declaration rejection) triggers one in-request rewrite-and-replay; the rewrite is single-shot per request and no per-host, per-channel, or on-disk state is retained. A rejected request never executed a search, so the replay is side-effect free and consumes no billed search quota.
Fixed
- Hosted-search responses whose url_citation annotations omit start_index/end_index no longer fail Grok Build's annotation parser: missing indices are filled with 0 on every route, in non-streaming bodies and streaming terminal events alike, preserving search availability at the cost of citation highlight precision only.
