This release adds an opt-in shared plans sidebar to the TUI, delivers multiple performance improvements across session handling, tools, and filesystem operations, and fixes several bugs including lost user config updates and OpenCode session header handling.

What's New

• Adds an opt-in shared plans sidebar to the TUI (settings.layout.show_plans), listing the five most recently updated shared plans with support for opening, refreshing, and browsing all plans

Improvements

• Avoids HTML escaping in JSON tool results, reducing unnecessary escape sequences in LLM payloads
• Trims redundant prompt text in the fetch tool
• Fixes O(n²) string conversion in URL prefix scanning (urldetect)
• Eliminates wasted strings.Join allocation in scrollview.compose for the two most common render paths
• Replaces strings.Split with lazy strings.SplitSeq in search_files_content to avoid materializing full line slices (~9.5% allocation reduction)
• Reduces attachment data URI allocations by replacing fmt.Sprintf with plain string concatenation
• Adds OwnMessageCount to count session messages without cloning the full message slice
• Adds AllMessageCount to count all messages across the session tree without cloning
• Avoids cloning the session tree in last-message lookups (getLastMessageContentByRole)

Bug Fixes

• Fixes sending of x-opencode-session header to OpenCode providers via a shared transport for all clients, gated on the host
• Fixes plans sidebar reconciliation with upstream tab lifecycle in the TUI
• Fixes lost user config updates after file-lock timeouts by serializing in-process Update calls with a mutex
• Fixes eval agent validation to occur before judge setup, so missing or invalid agent configs fail early

Technical Changes

• Warms PowerShell before hook tests on Windows to avoid cold-start overhead interfering with the 60-second hook timeout
• Widens the program-quiescence settle window in TUI tests under -race to reduce flakiness
• Records client lifetimes in AGENTS.md and points to the contributing guide
• Documents options.WithTokenSource in the Go SDK guide
• Trims comments in the OpenCode session transport, its tests, and the OpenCode gate/WebSocket fallback
