Grok Build 0.2.57

• [fix] Fixed cases where long-running conversation compaction could hang indefinitely.
• [fix] Notification hooks now fire only for real user-attention events and no longer trigger constantly during tool use.
• [fix] Fixed literal display of HTML entities such as < and > in responses and tool output.
• [fix] Typing [ in the pager prompt no longer appears delayed.
• [fix] Copy now tries all available Linux clipboard tools so paste works reliably in more terminals.
• [new] Improved resilience to network blips during long responses by resuming instead of failing the turn.
• [new] grok plugin install <name> now resolves plugins from registered marketplaces instead of only local paths.

Under the hood

• Documentation now shows 256k context windows in model configuration examples.
• Added otel_protocol setting (http/protobuf or grpc) for OpenTelemetry exporters.
• Clarified how the [hints] table participates in the effective config merge and how teams can pin values via managed or requirements files.
