docker-agent

This release adds sandbox authentication improvements, compaction-model context visibility in the TUI, MCP lifecycle enforcement, and a range of bug fixes across the TUI, CLI, and OpenAI integration.

What's New

• Adds sbx-login injection for gateway authentication in sandbox environments, replacing the previous file-based token-forwarding mechanism
• Defaults sandbox creation to the docker/docker-agent-sbx-templates:latest template
• Creates sandboxes under the canonical docker-agent name
• Makes oauth clientId optional for remote MCP toolsets, supporting Dynamic Client Registration and interactive credential flows
• Surfaces the compaction-model context-limit cap explicitly in the /context dialog and sidebar, so users can see when a dedicated compaction model is imposing a smaller context window than the primary model
• Adds segment-aware click detection on the sidebar Token Usage reading: clicking the token count/percentage opens /context, clicking the cost/⚠ capped area opens /cost; the "Token Usage" title is no longer clickable
• Enforces lifecycle.call_timeout for MCP tool calls, which was previously parsed but never acted on
• Exposes spawned TUI tabs (opened with ctrl+t) on the --listen control plane so control-plane clients can observe all active sessions
• Adds GitHub Copilot to docker agent setup and doctor, recognizing both GITHUB_TOKEN and GH_TOKEN

Bug Fixes

• Fixes copy buttons rendering in contexts where they were never wired up for hit-testing (reasoning blocks, elicitation dialogs, lean TUI, shell output, welcome messages)
• Fixes the "copied" flash background on user-message copy labels, which previously rendered with a transparent background
• Fixes mouse hit-testing falling out of sync when layout shifts without a terminal resize (e.g., after loading a past session with /session)
• Fixes an infinite loop in backgroundAt when encountering invalid UTF-8 bytes
• Fixes capability handlers (OAuth elicitation, etc.) not being forwarded to inner toolsets when code_mode_tools: true is set
• Fixes data races in deferred tools and the BM25 RAG strategy, and prevents a TUI editor panic
• Fixes wrapped URLs losing their clickability in tool output
• Fixes the ⚠ capped marker on the sidebar opening /cost instead of /context
• Fixes docker agent debug not appearing in the root help output
• Fixes docker agent setup provider path labels to clarify built-in cloud providers vs. custom OpenAI-compatible endpoints
• Fixes OpenAI Responses API function arguments not being recovered when providers omit response.function_call_arguments.delta

Technical Changes

• Refactors sandbox integration to assume the modern CLI surface shared by both backends
• Removes all references to the discontinued agentcatalog Docker Hub namespace, replacing examples with neutral myorg/agent placeholders
• Freezes config schema v14 and advances latest to v15
• Refactors board internals: deduplicates column lookup with a columnIndexLocked helper, deduplicates stored-project access with a projectsLocked helper, and consolidates per-card controller state into a single cardState map
