Sækja hellogrok-cli 0.1.25

Fixed
- Responses streams no longer fail when an upstream reuses one item ID across output slots (observed on sub2api-style gateways that share a single reasoning ID per response). The colliding later slot is remapped to a fresh unique ID that keeps the provider's type prefix (rs_, ws_, msg_, …), and every later item_id event for that slot — reasoning summary deltas, function-call argument deltas, and the final response.completed snapshot — is rewritten consistently. Affected turns previously exhausted Grok Build's retry budget and ended as Server error (500).
- Chat Completions streams now assign a unique call_ ID to any tool_call whose upstream ID was already used by another call in the same response, keeping the next round's tool history valid instead of tripping request-side history validation.
- The per-stream remap count is logged (remapped N duplicate upstream item id(s)) so a defective upstream remains visible in diagnostics.
Changed
- Responses stream identity validation distinguishes two failure classes: cross-slot ID reuse (remapped, stream survives) and same-slot identity conflicts (still rejected). Request-side tool-history validation is unchanged.
