hellogrok-cli 0.1.21 பதிவிறக்கம்

Added
- Internal SessionIdentity normalization for Grok Build requests. Stable conversation identity can come from an existing upstream session header, Grok Build conversation/session headers, standard session headers, or metadata.session_id.
- OpenCode Go upstream projection: custom routes under opencode.ai/zen/go now receive x-opencode-session when the incoming request supplies a stable identity. Existing non-empty values remain authoritative, and requests without a stable identity are not assigned a random per-request ID.
Fixed
- OpenCode Go custom channels no longer lose Grok Build's conversation affinity when hellogrok rebuilds the upstream request for protocol conversion.
